Cool, I sure wish this would happen to me!
RIght now I can't spring for anything in my dream category.
Under the one knife model it would be
A Strider MT; Don't know why I want one of these, I'd never use it since it cost me so much but they just look so cool.
or
A Bill Seigle Hoodlum;
Handled one of these and it makes a lot of sense. Like a modified Gurka design. Pretty damn cool. THis one I would use.
Or could use a shorter Criswell sword to go with my Katana.
Around 18" would be a good length.
Or possibly a 10-12 inch Bowie of the sort available from some of the community bladesmiths. Prefer forged.
In the real world I would be more practical. If you can call having too many knives practical.
No contest I would get a Dozier fixed blade, probably a Pro guide or a skinner. Lifelong user of the highest order,
and a Swamp rat Camp Tramp.
Of course many things could happen after I had cash in hand to alter this well thought out plan!!
