The smoothness of this knife is hard to believe considering the price. The multi row ceramic bearings make for crazy smooth knife with lots of blade stability because of them being much wider than single row bearings. So the knife is rock solid with no blade play side to side and no lock rock (up and down play) at all!! Also no detent lash and no pivot lash. The machining tolerances on this knife are extremely tight for such a low cost high production piece.Now for the part that makes this knife so good.If you like super slicey knives than the towser K is exactly that. It's a super slicer that's coming in at around 10 thousandths of an inch behind the edge... on that tall flat grind with 10thou behind the edge thickness this thing is a freaking laser beam of a slicer.A card board box slicing laser is exactly what this thing is. The primary grind taper is done very nicely and the knife isn't gonna thicken up quickly during sharpenings.... after say 4 sharpenings it will be at around 12thou behind the edge so still super slicey. I would say it will stay sub 20thou behind the edge for at least 20 sharpenings if you are just doing touch sharpenings where not much steel is being removed. If you reprofile it to 15 degrees per side it will come up to around 11.5 thou behind the edge and then light touch up sharpenings from then on out and it's gonna take a long time before you start getting a little thick behind the edge.It's nice to get factory knives ground that thin behind the edge, it's rare as a lot of companies won't do it because they are scared of people not thinking about what they are doing and chipping the blades badly because of applying heavy twisting forces to the edge. Heavy Twisting forces and 10thou behind the edge thickness is a no no.I'm glad kizer did this design it's excellent, all around they absolutely knocked it out the park and it's nice to have a budget super slicer.The copper one is to heavy so I returned it and got a richlite one, cutting about 3oz off the knife weight... onsale at 38 bucks it was such a great knife at that price I bought two more...If you are looking for an ultra smooth and mega slicey edc knife that is priced well under 50 bucks the Towser K is literally the best option out there right now. Even at its normal 70-80 price it's still a heck of a great deal but at sub 40 bucks?
