Okay. He's got what's called a pen knife, which is one of my favorite designs. Lots of companies have made them for a long, long time. Victorinox and Wenger make them, as well as Case. In my collection, I have some celluloid handled examples that are over 100 years old. Two blades, one long enough to probably slice an apple, sharpen a pencil, cut out a coupon, slice some cheese, cut up a sandwich, etc, the other a little blade that can do for a scalpel, dig out a splinter, clean and trim fingernails, snip a thread, and so on.
The one in my pocket today is a Case 32087 CV, with yellow delrin handle scales. I paid $35 for it last summer. That's my most expensive one, but I've seen one that had a pair of scissors instead of the little blade, and Mother of Pearl handles, and it was about $150. My cheapest one is an IXL with worn-out joints that I paid less than $5 for just because I liked the file work on the liners.
I have a little Wenger that is the thinnest pen knife in my collection. It has thin red aluminum handles, no scales, and just the two thin little blades.
