Tiny crack on pin knot
Hamish:
I can remember quite a few bows on PA over the years that broke in tension, or developed a chrysal right at a pin knot. It is true a lot of guys get away without compensating for them. I don't think it's by design or skill. It's sometimes safe because the bows are actually slightly overbuilt, or longer than normal.
The same guys that get away with it try it with a more highly stressed bow that is a little shorter, and or narrower, come on here and ask why their best bows have blown up when shooting. I had to learn the hard way too, before I figured out how to avoid the problem in the first place.
A pin knot is a literal break in the long grain, it just doesn't have the same strength as straight grain. It is an inherent weak spot. Compensate for it and you eliminate any potential problems. Its also a lot easier and cheaper in time and money than having to repair, or scrap a problematic bow.

Rough the back, and sinew back it now. It will be good for years to come in my experience, and I have violated back growth ring Osage bows sinew backed that have never failed me to date. Some 15 years old with a lot of arrows shot through them.
Selfbowman:
I’ve had my pin knots to deal with lately. The best is not to have them. But I’m almost all out of that wood!🤨🤨
Fox:
Yeah that’s my problem to selfbowman (Arvin? Is that your name, right?) good Osage is hard to come by around my neck of the woods

Plus one for me. Especially if it’s my hunting rig. You can always sinew back or hide back after the season is over for later more permanent fix
