I'm considering purchasing a large Bowie knife to add to my collection here soon, and have narrowed it down to these 2 choices. The Marble's Trailmaker is a 10 1/4" long, 5160 steel blade and stag handle for $135 and the CS Trailmaster is a 9 1/2" Carbon 5 blade and kraton handle for about $150. How suited are either of these as choppers and which would hold an edge longer?
