I've always struggled with sharpening scissors. Yesterday after
struggling to shear one of our fluffy little yappy mutts I took a pair
out to the shop and very lightly dresses it on 1x30 belt sander. Just a
couple light passes and it was perfect. It now will slice through
tissues paper hanging limp leaving a perfectly cut edge. The dog saw me
come back with scissors in one hand and a gleam in my eye, and headed
for points unknown...



If a belt sander works really well, I am somewhat reluctant to ask how
you were sharpening them previously.

Ummm,,, maybe look into making a mini-project of a Lanskey-style
sharpening setup for your scissors. You grind the (steel or stainless)
blades only with smooth ceramic stones. 30° is a fair guess, but the
angle varies from 5° to 45° with different models of scissors-

Aluminum-blade scissors are resharpened by putting them in the trash can
and buying a new pair. The faces (that are ground) and sides (that rub
together) both wear down so fast it isn't worth the bother. Their price
should reflect their disposable nature.
