I've been looking at the two knives Victorinox Centurion lock blade and the Victorinox One-Hand Trekker. What bothers me is that both have what i want but have exactly one problem. The Centurion doesn't have a thumb release, and the One-Hand Trekker has a wood saw that i wouldn't need and just takes up space. Is there a knife that has what i want but i don't know about??? I've heard of people buying custom Victorinox knives, how much is that anyway?
