I recently purchased my fourth Benchmade knife, the Contego in CPM M4 steel. It is a large knife but it has become my edc. I bought a red box BM several years ago, I'm not sure what kind of steel the blade was, but I think it was possibly a version of the Griptillian. My first Blue class BM was the Mini Barrage, second Griptillian with black blade and thumbhole, third mini Onslaught, and recently the Contego. I have experience with Spyderco products and they just didn't work out for me. I bought a new Native and the pocket clip fell off. Later on I bought an Endura 4 in VG10 steel. The knife just feels flimsy to me and it came dull. I wanted to like Spyderco but Benchmade has become my favorite manufacturer.
