Every so often the question comes up here about knives used in the Demolition Kits of various eras. While searching for something else today I ran across a manual I had entitled "Explosives and Demolitions" FM 5-25 published by the HQ, Dept. of the Army and dated March 1986.
In flipping through it quickly before turning back to my original task I noticed that it had a nice drawing of the contents of the Demolition Kit. That showed two folding knives, a TL-29 and a 4-blade utility knife. The latter does not appear to be a MIL-K. No real details were provided but at least we know what blades the Demo Kit contained in 1985. I thought I would scan and post the page so we'll have it here when the subject pops up again.
