Heater Shield
The History of the Heater Shield as a Symbol of Knighthood in Belegarth
Written and Researched by Retainer O'sha of Numenor and Edited by Sir Artemis of Numenor
Across the greater Belegarth community, the heater shield has become one of the defining symbols of knighthood. It is recognized as an emblem of the office itself rather than simply a piece of equipment, representing both combatant and noncombatant knights alike. As a result, it has become a common tradition for a new knight to receive a heater shield bearing their personal heraldry during their elevation. While not every knight chooses to fight with a heater, and not every knightly order follows the same customs, the association between knighthood and the heater shield has become one of the most enduring traditions shared across the sport.
The Belegarth tradition of knights wielding heater shields appears to have originated with the Knights of Numenor (KoN) in Champaign-Urbana, Illinois, with its roots extending back to the earlier days of Valdemar from which the Realm of Numenor descended. Both Valdemar and early Numenor maintained a strong hierarchical structure. Shield shapes were one way status in the hierarchy was expressed. The 1992 Valdemar rulebook explicitly states that only knights were permitted to use heater shields, while non-knights were restricted to round shields no larger than 28 inches in diameter. Likewise, the 1996 Numenor Dagorhir rulebook reserved both heater shields and the display of heraldry on shields exclusively for knights.
Although the privilege of carrying a heater shield was clearly established in Valdemar, the shield's exact shape was not. Neither the 1992 nor the 1996 rulebooks specify standardized dimensions or proportions. Contemporary photographs and surviving examples suggest that early knightly shields ranged from historically inspired kite shields to broader forms that more closely resemble the modern "home-plate" heater. Other prominent early realms, such as Pentwyvern and Avalon, also had knights who carried heater shields and displayed heraldry, but their use was neither universal nor required for knighthood. In this regard, the KoN appears to have been unique in making the heater shield a defining symbol of its knightly order. Numenorian knights were required to have their heater shield—along with a full set of armor and a surcoat sewn in their knightly colors—to be inducted into the order.
The now-familiar KoN heater shape seems to have emerged gradually during the mid-1990s. The Tome of Numenor* depicts early knights like Sirs Kalvic and Kegg carrying elongated kite shields painted with their heraldries. First-hand accounts suggest that the modern heater evolved from these earlier historical shapes rather than appearing fully formed. Multiple elder KoN independently recalled that the transition toward standardized heater dimensions began around 1994 or 1995, when Numenor prepared for its national debut at Ragnarok, Dagorhir’s flagship event. According to these accounts, many existing knightly shields were rebuilt with the modern “home-plate” heater dimensions so they would share a common shape and construction for bridge battles and shield-bashing competitions.
"Our shield-making methods were much different before branching out to other national events, so we made these gigantic super-padded versions with plywood for that event... that was my first heater shield." —Sir Treethump (knighted 1993), recalling receiving his first heater shield during this period.
As for why the KoN originally adopted kite shields—and later standardized on the home-plate heater—there is no surviving documentation that provides a definitive answer. The consensus among those interviewed is that the decision was, at least initially, driven by aesthetics: they thought it looked cool. The shape complemented the historical image they wanted to project, visually distinguished knights from the citizenry, and provided an ideal canvas for displaying heraldry. The modernized home-plate heater design also carried several practical advantages at the time. It offered a middle ground between a smaller, lighter round shield and the big door shield favored by many other realms’ line fighters and bridge fighters. Because coreless shields did not yet exist—all shields were built with half-inch plywood cores—the difference in weight was significant. The heater made KoN lighter and more mobile than the much heavier door shield fighters, and, with proper training and conditioning, offered comparable protection. At the same time, it retained enough mass to be an effective shield-bashing tool for bridge battles and breaking enemy lines, and it resisted displacement well against the mass-oriented weapons of the era. Its additional corners and extended lower profile also provided better leg coverage and created defensive angles that were not possible with the standard 28-inch round. Altogether, the home-plate heater’s battlefield performance fit the image and tactics of the time, allowing the KoN to move quickly while still maintaining an armor and shield size advantage over a large percentage of the field.
“My first plywood and foam heater in 1998 weighed just under 14 pounds. Some heaters from a construction technique a full generation before mine were even heavier. So, in the context of the old days, some of the thinking in restricting the heater shield was to help people develop the ability to actually use the heater. Most folks in the old days just held big shields in front of them statically, sometimes resting them on the ground. The fighters with big shields didn’t move them much since the plywood door shields could weigh 20-30 pounds, depending on construction.” —Sir Artemis (knighted 1998) recalling his first heater shield.
Some of the home-plate heater’s utility had to do with demographics and economics. With no complex cuts or curves, the home-plate shape could be easily described verbally and cut by someone with hand tools and little to no experience. In a pinch, a person with no access to tools (e.g., a college student), could describe the shape to a helpful attendant at the lumber store, who could cut the plywood at the store for a small fee if they weren’t busy.
The spread of the tradition beyond Numenor appears to coincide with the rapid growth of inter-realm travel during the mid-1990s, and, later, the commercialization of the sport at large. Around 1994 or 1995, Numenor attended its first national event, Ragnarok X. As Sir Artemis, knighted in 1998, recalled, "from then on we were a cultural presence in the sport at large." Between approximately 1994 and the Dagorhir–Belegarth split in 2000, Numenor was widely viewed as an influential realm whose practices were frequently imitated. The culture and traditions of the KoN spread both directly and indirectly. As KoN moved away from Champaign-Urbana, they founded or joined new realms, took on non-Numenorian squires, and knighted them as bastard knights of Numenor. Further, during this period, it was common for realms to adopt traditions they admired from one another through interaction and observation at national events. Based on multiple accounts from elder knights, it is likely that many realms adopted the practice of bestowing heater shields for knights after seeing the KoN's distinctive use of them at national events.
The standardized shape of the modern Numenorian home-plate heater is also, in part, a product of the sport's modernization and commercialization. Much of the variation seen in shield designs throughout the 1980s and 1990s stemmed from the fact that nearly all equipment was individually handcrafted. While some realms had dedicated foamsmiths who built gear for others, very little standardized construction existed. Before the introduction of laminated half-inch foam, every layer of every shield and sword was individually templated, hand cut, and glued—often with varying levels of precision and craftsmanship. As a result, even equipment made by the same craftsman for members of the same unit or realm often showed noticeable differences in size, shape, and proportions.
That began to change in late 1999, when Edhellen Armory (now Forged Foam) introduced the first commercially available shields and swords manufactured from machine-cut laminated foam. With close ties to the influential Numenor and the new founding of Belegarth, Edhellen's equipment was readily adopted on a national scale. For many fighters, purchasing professionally manufactured gear was faster, more consistent, and far more accessible than acquiring the materials and skills to build their own equipment—or waiting for a local foamsmith to do so. Importantly, Edhellen's first widely distributed commercial heater shields were patterned after the dimensions of the Numenorian home-plate heater then favored by the Knights of Numenor. As these shields spread across the country, they helped cement the Numenorian pattern as the de-facto standard heater shape.
Modern heaters in Belegarth take many forms, with significant variation in size, construction, and style. It is common to encounter uncored foam heaters, traditional plywood heaters, and stylized Plastidip-coated heaters with a wide range of heraldry designs and strap configurations. Despite this evolution, the influence of the Numenorian heater remains unmistakable. What began as a local tradition—born from a blend of historical inspiration, battlefield practicality, and knightly identity—spread through standardization, propagation, imitation, and eventually commercialization to become one of the defining visual motifs of peerage in the sport. Although the equipment has continued to evolve alongside advances in foamsmithing and fighting styles, the heater shield endures as a recognizable symbol of knighthood, linking generations of peers together.

The following is a conclusion drawn from a thread on the Belegarth Boards, ([1]) on the subject of making a heater shield.
Common Misconceptions Addressed
Heater shields are extremely popular with knights (in Belegarth), but contrary to popular belief many non-knights used heater style shields throught the middle ages. So, it isn't "blasphemous" to own a heater shield and be "non-chivalry" (To Para-Phrase Magnus of Taurendor).
This is a direct quote from Kenneth, which may clear some things up.
"I think I may know what this is talking about. Geographically, the realm of Loderia is very near to the realm of Numenor. The Knights of Numenor all bear heater shields. I believe it is an official realm rule that non-knights may not use heater shields. We also have other shield size restrictions. That is why most, if not all of the squires of Numenor use round shields, not heater shields. Just about the only time a non-knight is allowed to use a heater is when they are near to their knighting. The heater is a status symbol of their knighting. I believe this tradition is followed in at least a few other places.
Personally, I don't find it extremely offensive for a non-Numenorean to be using a heater shield. However, I do have higher expectations of heater users, and I do make it a (small) point to try and take down heater users first. My motivation for doing so is practical. Knights(Especially in Numenor) do more damage on the field than non-knights. Kill the knights, and a team will be at a serious disadvantage. This strategy has the happy side effect of discouraging non-knight heater usage.
On another practical matter, using a round shield until knighthood teaches footwork and how to guard your legs with a smaller shield. I would say the average level of footwork in the average Numenorean is significantly higher than the average footwork in other realms simply because nearly everybody uses a round shield. When you take away the big door shield from many fighters, they become easy kills because they can no longer simultaneously defend their legs and their body.
I wouldn't necessarily say I frown on non-knight heater shield users so much as fighters who use a heater and don't have anything to back it up. I have higher expectations for those who use heater shields, and I make my disappointment felt if the user doesn't meet my expectations =P.
If you're actually in the realm of Numenor though, prepare to be a walking target."
What They Look Like
Belegarth heater style shields generally look like this:
Note: The shield held by Winfang (above) is a 28" x 36" shield.)
Real heater shields tend to look like this, with a curve and more of a slope than angles.

Dimensions
Now, you're probably wondering how to build a heater shield, the standard design is something like this:
(Note: These are dimensions for the core.)
These dimensions are not set in stone. You can make your heater any size you want, as long as it passes the Book_of_War standards. But I suggest adding at least two inches of padding on the edges, which adds 4" on both the length and width of your finished shield.
Core
Now that you have the dimensions for a heater what kind of core would be best? Most people use Tech-ply because it is stronger than regular plywood and lighter. Techply is best for shields in the 5-ply thickness, and at .25" thick it is half as thick as a normal plywood core would be. If Techply is unavailible standard plywood makes a decent shield.
Handle Placement
Handle is extremely important because it drasticaly affects the way the shield moves. Most people use the standard grip, which is parallel to the ground and low enough on the shield to cover your shoulder when your arm is at a right angle. When the handle is parrallel it keeps the tip of the shield infront of the user's body automatically protecting the user more. See Constructing_a_Strap_Shield for details on constructing the handle.
