That is rough. Poor Biscuit probably has no idea he got turned into a jungle cat. I tried one of those free ones on a pic of my old lab and it gave him extra toes and a weird eye, so you are not alone. The paid ones seem to do less guessing, but honestly I have had better luck just using my phone's built in sharpening tool and leaving it at that.

Brought a 5lb ball bearing to check a 150lb Peter Wright last spring. Dropped it from about 10 inches and got maybe 6 back, walked away. Seller was annoyed but that anvil had a dead spot near the horn from a bad weld repair you couldn't see otherwise.

Man, my first run with headless on maple went so bad I almost went back to finish nails and a prayer. What saved me was switching to Titebond III with just a thin bead, then clamping every joint for a full 30 minutes instead of rushing it. The glue line matters more than the pin size on hard maple, since the wood barely moves once it sets. I still get a tiny dimple on fill now and then, but a wet rag and a light sand takes care of it.
