Both of these are Kershaw pocket knives with stainless steel blades, nylon handles, black coloring, and a limited lifetime warranty, so the choice comes down to blade style and size. The Camshaft 1370 runs $39.99 and has a 3 in straight edge blade, while the Conduit 1407ST costs $46.99 and features a 2.9 in partially serrated blade.
The Camshaft suits anyone who wants a straight edge blade with a longer 3 in cutting length and a 7.25 in overall length when open. The Conduit is the more compact and lighter option, at 2.6 oz versus the Camshaft's 3.1 oz, with a shorter 3.9 in closed length, and it adds partial serration for those who prefer that edge type.
