sharpening aviation tin snips

[bnlsrv]

Anyone try sharpening tin snips? I believe mine are offset, aviation wiss snips. Or Malco.
Would the scissors technique work? Mark with a Magic marker, etc for the angle.
Thank you

I took apart my snips and got a pretty good edge. One side I was able to use the Svd-110 to help keep the right angle. The other side was too difficult to do using any jigs or supports. But, they cut like a dream now!


As I look at my other snips the edge appears to be flat so is there any problem using the side of the stone to do this free hand, rather then the top of the stone?
