Read a soil guide saying caliche vs fill dirt changes everything, and "it never moved once" means nothing without knowing what's under it.

Single bevel knives are a whole different thing, not just sharpening. The flat back needs to stay dead flat or the edge folds on bones like that. But yeah, an $85 deba is not going to beat a cheap boning knife on salmon. Those things are made for one job, and salmon spines are not it.

Totally get that! Had a similar wake-up call with a navicular case. Switched to a full support pad and a straighter bar shoe, made a world of difference.
