The Friday, Saturday, and Sunday night shows you've been using as examples, were featuring the piece of crap razors that both Todd Boone and Tom O'Dell were hawking, and they MISTAKENLY said, time and again, that a straight razor's hollow grind is measured from the spine to the edge.

How else would you explain the addition of a woman who has all of the charm and personality of a book of stamps. Knowing virtually nothing about knives, Mrs. Travis points the seemingly slowly sinking into senility O'Dell in the right direction when she isn't busy yakking off camera with whomever happens to be in the room.
Cutlery Corner. The epitome of FAIL.
