Stainless steel handle holds blades securely. #3 handle holds #10 or #12 blade, the No. 4 handle holds #20 or #22 blades. These blades will not fit a Beaver handle. Blades are carbon steel.
"#12 Scalpel Blades"
Sharp, clean and effective. Can't ask for much more. They hold onto the handle really well and don't slip around. I use the #12's for hog castration, and they take less than 2 minutes, with little to no blood.
