1. The test you speak of was rigged using liquid nitrogen (the only reason a Yarborough/GB would shatter under batoning or snap in a normal bend test)
2. The 'tester' was one of the makers who did not win the contract and to this day is unhappy about it (even though he makes a fine knife)
3. don't believe everything you see on you-tube - there may be more to the story.
My GB and Yarborough have (like TR's) been used for many things they were designed for and perform spectacularly, sharpening is not hard to accomplish, but I'm not putting either of them in a vise... they passed that test in getting chosen for issue (a standard part of the Knifemaker's Guild Test for Master Bladesmith).
The newest of the Yarborough's and GB's are in an even better steel...
What point are you trying to make?
BHT.... watch that capitalization on Troll... Troll (me, capitalized) does not equal troll (internet rodents)... as you can tell from my marvelous picture.
