I have one right infront of me. It is a large tanto. I love these knives. I find that many knives out there aren't really designed for human hands! Take most SAKs for example. Awesome knives for sure, but look at the "handle". Now compare that with a handle on other tools: say a shovel or a hammer. See the difference? So I love Buck/Striders because the handles are thick and wide. They fit your hand very well. People often comment that the Buck/Striders are big and heavy, but that is in comparison with Benchmade Osbornes and Spyderco Enduras. Compared to other tools, these knives are the right size!
The lock-up on mine is solid. The locking liner is something like .08 inches, very very thick comapred to most (all?) other production liner locks. OI also find the handle to be quite rigid. I liek to squeeze and twist my folders to see how much the handle will flex and how the lock distorts. My Buck/Strider has very very very little flex.
Recently these knives were improved. They now come with double thumb studs, smoother handle scales, a diferent wsher set-up, and the locking end of the ti liner is heat treated to make it harder. All of these improvements make the Buck/Strider folders one fo the best production deals going around. Right now I am trying to decide whether I should save for a Buck/Strider spearpoint, or save for a Strider AR, or the MARSOC. What makes the decision tough is that the Buck/Striders are such good deals! I heard one forumite descibe the Buck/Strider spearpoint as being 2/3 of a Strider AR, at 1/3 the price.
For utility usage I'd suggest the Spearpoint over the Tanto. I love my tanto, but if I could only have one, I'd take the spear point.
Good luck!
