Based on that explanation, I'd call the little guys "The Scrapper X Series", generically described as "a wharncliffe style blade of varying blade geometries made from custom knife remnants, each knife being as unique as the remnant from which it was carved." A Scraper X would a blade X to X.999", e.g., a Scrapper 3 would be any Scrapper with a blade length of 3.xxx"
Expanding your marketing options, --
"Scrapper WX", for a wharncliff scrapper,
"Scrapper CX" for a clip point,
"Scrapper DX", for a drop point,
"Scrapper TX", for a tanto point
"Scrapper SX" for a spear point
with the point style based on what could be most easily made out of the scrap piece available.
No thanks necessary for this moment of marketing genius, just a prototype of each point style in each length from 3 to 6 inches, to start my "TM Hunt Collectible Blades" display.
