![]() ![]() Some blades will take and hold sharper edges than others and the thickness of the blade will determine how wide the bevel will need to be. The resulting edge is somewhat dependent on the particular blade. The result is typically “very sharp” with a small secondary bevel and a bit of an “apple seed” profile. Our sharpening service will provide a good serviceable edge on the blade. Consider this as a general guideline only. The Edge ratings in particular are somewhat subjective and each blade can vary. This info is provided to give you a good idea of the product being presented, the one you receive may vary from the specific one we took measurements of. Please note: Due to the hand made nature of these items, all specs should be considered as approximates. However for reasons we won’t get into here, this is not the case. ![]() A common misconception is that swords should all be “razor sharp”. Moderately Sharp is close, but may need to be touched up to get the best performance. Possible values could be “Rebated” meaning the edge is intentionally thickened for safety, “Blunt” meaning the edge is fairly thick with little to no taper, ‘Unsharpened” which would taper to the edge but stop short of having any real cutting ability, “Slightly Sharp, Moderately Sharp, Sharp, or Very Sharp” Sharp or Very Sharp are considered good for cutting swords. The “Edge” spec will tell you about how sharp a blade is. A very high POB will result in a sword that feels heavier than it actually is and is difficult to wield. In general, a low POB results in good point control well suited to a thrusting blade, while a higher POB adds impact to a cleaving blade. A POB of 3”- 5” usually results in a well balanced sword, but does depend on the type of sword. In practice however, there are many reasons why you may not want this for a particular sword. In theory a sword with a POB of 0” is perfectly balanced. A number of 0” would balance exactly at the guard, while a negative number will have a POB in the hilt itself. It refers to the point on the blade where the sword achieves a perfect balance. stands for Point Of Balance, this is measured in inches from the hilt down the blade. The wood Saya has been coated with black lacquer and its koiguchi, kurikata and kojiri fittings are of polished buffalo horn. A full wrap rayskin, while common historically, is now quite rare among reproductions. The ito has been overlaid over a full-wrap samegawa rayskin and two lizard menuki are wrapped between the ito and tsuka. ![]() The tightly wrapped ito is of natural black silk that has been imported from Japan – underneath, it has a the paper triangle hishigami to ensure a traditional, and tight fit. Its tsuka grip has been hand carved to fit its specific nakago tang. ![]() The Katana fittings are hand cut and shaped from pure iron. This helps ensure that the blade can be robust enough to cut harder traditional targets, such as bamboo, repeatedly whilst resisting chipping of the edge. This tapered spine also allows for the blade plane between the shinogi and the edge to be thicker, thereby creating a strong and druable style cutting edge with emphasized ”Niku” without upsetting the balance of the blade with the added thickness. This was negated on the Lotus Katana by giving the blade a mune spine that is tapered on the blade plane between the mune spine and the shinogi central ridge, which runs down the middle of the blade. While a blade lacking the Bo-Hi makes for a blade with robust geometry it does make for a heavier blade. The solid blade has been optimized for repeated cutting durability by omitting a Bo-Hi groove. It is brought into its full beauty by a traditional polishing using a combination of natural and synthetic polishing stones. The blade, differentially hardened by the traditional clay tempering method, is crafted from 1075 high carbon steel. It has been signed by its smith on the blade nakago, along with its production number. Optimized for the practitioner of Tameshigiri who wants a stand-out sword, the Lotus Katana from Citadel Knives and Swords is limited to a production run of 100 swords. ![]()
