Grafting knife

This small hand tool - a sort of miter box - can help you cutting the branch into the perfect angle (15°) when grafting apple, pear, plum trees etc. The Knife blade is a Stanley no. 1992 - a blade for a standard utility knife. 62 mm long and 19 mm heigth: https://www.stanleytools.co.uk/product/147165
2015.03.31: The 2 parts are updated so that the knife blade can only go as deep as the branch is.
2015.04.03 Seven small apple trees were grafted with one year old "sleeping" branch
2015.05.24 first new plant shoots from the grafted branches :)
2015.06.07 now plant shoot has grown into leaves. 2 out of 7 branches have leaves on - the other is still sleeping.
Pls. let me know what you think.
