I have a large tanto folder.
Lock-up is solid. Blade is sharp. This knife really shines as a tool. On many folding knives, the handle is thin and small and cute. On the Buck/Strider, it is large enough for your hand to really grab a hold of the thing and use hard.
I usually have my SAK in my porcked while I'm carrying my "tacticals", so I like the thick tip for hard use if I need it. If you aren't going to carry another knife for finer work, I'd suggest the spear point. Also, realize that the knife is 3/16" thick. My Buck/Strider doesn't cut like my nice thin Scrade Old Timer blade. Then again, the Old Timer would easily break with some of the rougher chores I have put my B/S through. I believe the spear point is hollow ground, so it might be thinner at the edge than the tanto, I'm not sure.
By the way, Buck recently changed a few things with the folders. Now you can get partial serrations. But one of the important things is the texturing of the scales. The older version has more aggressive texturing that offers a super grip, but they can chew up your pockets. The new version has a less aggressive texturing.
These knives are very much a quality product. Buck knows how to make a knife, and Paul Bos does the heat treating. Also, any problems people have had with their bBuck knives have been quickly taken care of, from what I have seen on the forums. If the Buck Strider is what you want, then go for it. You won't be getting a POS, you'll be getting a quality product.
