The brisket, being the very meaty part between th efront legs of a beef, is a rather large cut, and those chefs who deal with them, want to make single pass cuts..no haking, so ittakes along blade to make the cuts clean.
Evidently, the chefs ordering his brisket knives, are slicing almost as a demonstration for high end restaurants, and they like them lengthy and extremely sharp.
They are not relegated to briskets only..
Apparently, when done this way...it is like grand prize trap shooters.. the engraving and gold inlay doesn't necessarily make the shotgun more capable...but it has plenty of "wow factor" for some folks !
I don't know what the handle is, but I am sure it is an exotic wood, which he has stabilized with acrylic under vacuum.. I'm guessing it is Amboyna burl..but won't swear to it !
I am not big on meat as a food..but I sure do enjoy corned beef brisket...especially in a well assembled Reuben sandwich..on rye please..
