Panel saws teeth
Inherited two panels from my grandfather after his passing. I’d like resharpen and repair them for my own use and I’m familiar with sharpening techniques and saw anatomy so I don’t mind the learning curve and I don’t want to spend a lot of money for new modern saws. My question is: based off the teeth structure which saw do you think is profiled for a cross cut and which for a rip. Both saws have features of each profile. The non cracked handle pic 1&2) is a Disston saw with a known 8 tpi. The cracked handle panel (3&4) is unknown brand and unknown tpi. The disston teeth face looks uniform and chisel-like but seem to have a bevel alternating. The unknown saw doesn’t seem to have a bevel on the side profile of the teeth but the face of the tooth is more triangular shaped than chisel. The tooth set of the unknown saw also appears to be more wide than the disston and has less ppi from what I could tell. Could a better trained eye help determine which is which or should I just reprofile each saw according to the TPI?
