MT-151 vs red brick : winner = MT-151

This is a video-request and is part of a discussion which stemmed from a forum thread : http://www.cliffstamp.com/knives/foru... which cited this video :    • Видео   To be clear this video (mine) doesn't demonstrate extreme toughness of the MT-151, it is more of an attempt to show that in order for these demonstrations to be useful and for you to know if in fact the knife is tough you would need to know two things : -what knives could not do that -what other knives could do that To be really specific, ideal questions to ask (and know the answers to) are : -what is the least knife which can "pass" -what is the most knife which can "fail" This is needed to put the work in perspective. It is also argued that in general, very general, if a maker/manufacturer is going to do such work and use it to promote a product they should be willing to state that the work can be expected to be representative. If as a consumer you do not have such a statement then what exactly can you infer from the demonstration? Note at the end when I say "this type of work" I don't mean chopping up bricks, I mean comparison work where reference blades are used so as to provide meaningful benchmarks so someone watching the video's can see if what is being shown is low, moderate or high performance. In regards to the geometry, the first cut, if you look closely produces some edge damage, but again this is a very slim geometry, what I normally run to cut wood very efficiently : -4 to 6 dps at the shoulder of the bevel -8 to 10 dps at the apex of the bevel The damage was less than 0.010" thick on the rock contacts inside the brick so I applied a secondary bevel of 20 dps. This bevel was 0.010" thick. It was intended to be only about 0.005" but a 36 grit belt doesn't afraid of anything. In general a decent starting point for an over bevel to prevent damage is about half the thickness of the damage seen.
