Dale brings up a good point.

Sgian dubhs are inherently lnked with Scotland and more specifically with kilt wearing. They were not intended as weapons but tools and, therefore, Rule 11 does not apply.

Claymores (whether the broadsword variety or the hand-and-a-half variety) are inherently linked to Scotland but always were weapons...but they are also associated with kilt wearing, albiet strictly in an historical context.

Dirks, again, linked to Scotland and kilt-wearing, although largely ceremonial and seldom seen today, were weapons but still part of traditional Highland dress.

Firearms (NOT modern arms like, for example, the AR-15) are, again, historical but always intended as weapons or hunting tools. They are pretty much only appropriate within the context of historical reenactment and educational or scientific demonstrations and common sense should prevail. I highly doubt a kiltie is going to tote around his Brown Bess on a daily basis.
Archery kit falls under the same criteria as firearms for the reason that the intent during operation is the same, only the means of the projectile's propusion are varried.

Yes, hunting and sports are still daily activities for millions of people but unless it's done in a kilt then it should go under the misc. category...or on another board.
If it's in an historical context then perhaps it should be filed under the historical sections.

What about making weapons?
These are clearly DIY projects. Many of these skills are dying arts that should be preserved for posterity and for educatinal, historical, and scientific purposes. therefore, their study and recreation should be fostered and encouraged...just use common sense about it.
