After carrying a Strider SMF for 7 years, I carried a Hinderer XM-18 3.5" Spanto for three weeks while the SMF was at Strider for a 'tune-up'. The SMF has a very useful and 'safe' choil that I use all the time when choking up on the blade for delicate work. The Hinderer? I cut the hell out of my finger the very first time I choked up on it. Totally my fault but the Hinderer choil, in my opinion, is dangerous. Lesson learned!
