You got it Ward! Most of these terms, often adopted by collectors to describe swords by typology are general terms used in varying cultural spheres for that weapon in general. The term shotel, as noted, means big knife, Gurade is said to mean curved sword, and as always, sa'if means in Arabic...sword.
We have discussed these terms and tried to establish consistancies futally for years.
Now, the big question is.....will Chevalier respond to this one!!!
