A Quick Guide To Shear Care
Convex shears have a different edge all together. This edge is a razor, and is also sharpened differently. Convex edges are honed on both sides, first on the diamond wheel to create the edge, then honed on the interior of the blade to make that edge a razor. Convex shears have little or no space between the blades because they are so sharp they “chop” through hair rather than slicing to produce a beautiful cut used in finish work. Tension is adjusted to where the blades start to grab 1/3 to ½ way down from the tips keeping the blades as close as possible to each other. If the tension is too loose on a convex shear two things can happen: the blades may grab ¾ of an inch from the pivot creating a gouge, and they can fold hair at the tips.
Note: The tension adjustment is for adjusting the way the shear cuts, its not for the convenience or ease of the way the shear opens and closes. Tension can be adjusted a little, but if its adjusted so the shear feels loose to you because of hand or scissoring problems, thats not good. There are shears available with ball bearings in the pivot.
This type of shear feels loose no matter what the tension is adjusted at.
Clean your shears daily. Wipe all the hair from the inside of the blades, this attracts moisture which can rust your shears. If the blades have grime or hairspray on them, take a Handy Wipe and rub all this off. Never leave shears dirty because it will cause problems down the road.
Lubricate shears with shear lube only, it contains silicon and a light solvent. Not lubricating can cause the screw to rust and not stay tight. There is moisture in your pivot from scissoring, lube gets rid of it. Not lubing can cause tiny pieces
