I got a great deal off ebay. -25 Testors #11 knife sets each w/one handle and six blades in a carded package, all for 15 bucks.
Come to find, all the #11 blades have this odd "tanto"-style tip. It has an extra angle just below the tip. Takes some getting used to.
I still have a100-pack of Excel #11's in the shop, so no big 'ting.
