Hello Zoomer, if you were driving through Stockton today it would be in shorts, the sun has at last arrived.
Sharpening tools, you need a good medium file and a smooth file. With shears take the bolt out and clamp one half of blade in a vice with the bevel towards you. With the medium file in line with the bevel rub the file forward across the bevel in slow circular movements do not press too hard making sure the file stays flat on the bevel. Now do the same with the smooth file until the cutting edge looks free from nicks. remove the blade and turn so the cutting edge is facing you and rub gently with the smooth file to remove any burrs caused by the first filing. I then run the bevel edge on the oil stone which in my case is boxed so can be clamped in the vice and running the blade along the oil stone, again in a circular motion. Re assemble the shears and make sure the tension is correct I do this by cutting paper as you would with scissors, if it does not cut first time adjust the tension on the bolt which should have a spring washer between the nut and the blade.
It is exactly the same to sharpen secateurs though with some modern types they cannot be taken apart,, there is no need to do that if you do not want to but the sharpening is always from the bevel side and not the back of the blade. Nine times out of ten hardening up the centre bolt gets them back cutting, I found about three times tighten the bolt to once sharpening the blades.
Hoping this gives you an idea as to how it is done any questions come back and I will try to answer them.
