I pretty much finish all the survivors
Occasionally I'll do an experimental bow that may get shelved in a shootable state, but then finally tarted up if it is to get serious use.
I recently tidied up a waggly old stick bow for field shooting as it was a few pounds lighter than my usual and I had a sore shoulder so wanted a lighter bow.
I have one that will take a full 32" draw that has been waiting about 3 years for a grip, but I only use it once or twice a year.
Depends on how you define finished

Took me 40 years to put horn nocks on my first ever Yew ELB
