I bought a smooth edge for my brother and a half serrated one for myself, both aluminum handle and spear point. The spear point has a very sharp point. I'm not really partial to tanto shapes, but the small one looks interesting. They sharpen fairly easily, take a very sharp edge, and hold it fairly well. I've only had to sharpen my brothers 3 or 4 times in about 2 years. Then again, he is not very picky and not abusive to it either. The half serrated one I had came with a very sharp smooth section, sharpened only on one side. It is very thin and will cut even after it has lost its razor edge. No lock trouble for me. I think the liner lock is made of steel, not Ti. The handle feels good to me, and fits my average size hands well. The only down side I found is the bead blasting. Polished aus-8 resists rust quite well. The bead blasted aus-8 of the M-16 developed some rust spots after a couple of days in my pocket. They cleaned off w/out any pits. Also, take into account that I carried it in my pocket during several 12-14 hour days in 95+ degree weather and was soaked in sweat after about 2 hours. I found it to be a good knife. It was just under the size that starts to poke you in the leg when carried in a front pocket. Also, the edge angles, even though only on one side, fit the sharpmaker right from the factory. Oh yea, one other down side. The tip is very sharp and quite thin as well. I broke mine off scraping some paint from around a window. It took about 3 weeks to put a new one on with a dmt blue stone, all by hand.
