Ok Wig, I'll bite.
I'm no knife expert, but I do like the lines (I'm a fan of flattened Persian/S Curve type blades). Looks like it wood be a good heavy duty combat blade if you're doing a lot of slashing, especially with the extra long handle. Probably not a whole lot of practical use but there's definitely a market as proven by the Busse AK, Ruck, Argonne(?) - am I right?
How about the Hellboy blade paired with a functional version of the knife Strider carries in LOTR?
ps - Welcome to the weekend!
