It's dark, you are tried, stressed, and maybe your hands are shaking. Do you really want a scalpel blade in your hands trying to make a handle so you won't cut yourself when cutting other things?
I scraped the scalpel blade in my Ritter kit and added a well sharpened alox classic SAK and thinned scale Bark River Mikro Slither (orange scales with hollow pins for a lanyard) in a small Kydex sheath to my kit. A Vic money Clip SAK also fits in place of the classic. The above take little room and IMHO, are far safer and better than a bare scalpel blade. The knives should fit in many tinned kits or pocket kits..
