I played my mandolin for a little while, until my fingers started to hurt. The top strings are thin and feel sharp. To deal with it I need some calluses.

“Calluses develop from repeated friction, rubbing or irritation and pressure on your skin.” (Cleveland Clinic)

Traditionally string players develop calluses from playing their instruments; one recommendation is to play for 10 minutes multiple times per day, rather than one long session. I would love to this, but my schedule doesn’t always allow for that, and I am easily distracted. I started to look for other ways to apply sharp pressure to my finger tips. I tried several home grown things, a block of wood wrapped with old guitar strings, a hand strengthener wrapped with wire, but they did not fit easily in my pocket and so would not be readily available throughout the day. I ended up making a triangular stick.

I squared up a small piece of flame maple to 3/4”, then cut it down the middle to make two triangular shaped sticks. I sanded them to 320 grit and sealed the wood with feed-n-wax. I made two lengths, one to sit by my chair, and the shorter one to go in my pocket.

To get the edge of the triangle to bite into my fingers, I place my thumb at the wide base and my fingers on the apex.

It takes a month to develop proper calluses, so I will update y’all later on the efficacy of this method. I can say that in the past few days I do pull out the stick (I need a better name) and use it several times a day. Even if calluses don’t develop, it makes a useful fidget.
