This thread moved me to clip Willies 'Big Spur' which very long, curved, and sharp.
The other must have gotten the sheath twisted off somehow, probably on some HC, as it's much shorter.
Am lazy tho and didn't want to wrestle him tonite, so just grabbed the guillotine dog nail clippers and did it while he stood on the roost. Took the very tip/point off the short one and 4 or 5 ~1/16 to 1/8 snips off the long one...no bleeding, didn't risk going too far.
Might do more tomorrow night...gonna be well above freezing.
