Why not make one?
On the Instagram woodworkers about a year ago there was a Make a Mallet Challenge with a small prize from Scott of Kustom Creation of some of his products. I made a “toymakers mallet” roughly using a plumbers mallet as the inspiration.
Here are photos of my mallet.
I’ll try to find the Instagram post if you’d like and send it to you, let me know.
Cheers Peter
