I would like to see a full flat grind, choil-less, 1/4" thick combat knife. With about a 6 or 7 inch blade. Maybe something like the SOD or Scrapper 6 with just the finger guard and no choil.
A fighter?
If we're going down that path then how's about a Dog Razor?
I love those Hell Razor lines, but at $300-400 a copy it's hard to justify too many.
A 'Yard version would be awesome, SR77 or SR101, respirene.
Keep the fuller, not fussed about the corrugations - I like 'em but I'd guess they'd add to expense and I could easy live without 'em, but I really like the fuller.
