« Part 12: Etc. Part 13 of Shopmade Luthier Tools series Part 14: 2 chisels rehandled »

A violin opening knife is a very thin, semi-flexible wide-bladed tool used to separate the parts of a violin. The glue used to hold such instruments together is brittle and will let go under stress. Apparently that is a feature, not a flaw.

For mine, I was too cheap and impatient to find a thin cheese knife, so I took a dollar store spackle knife and after removing the blade from the plastic handle and trimming it down, I sandwiched it between two pieces of mahogany with epoxy. When that was set up, I shaped the handle and further thinned down the blade on my belt grinder. N.B. he blade is not sharp, but just very thin to get between the joints of the instrument. The finish was boiled linseed oil.

Excellent, there is great satisfaction in making things and even more when you use tools you made to do it.

Agreed. What like the most about it is that no one else will have one exactly like it. My design, my style!
