Reliable knuckle duster

In stock it is made for 21.5 mm index finger in width, so you should scale it for your hand using the formula: a-your index finger width (in mm) (a+1.5)/23 x 100%

for example I have 18 mm index finger: (18+1.5)/23 x 100%=19.5/23 x 100%=0.847 x 100%=84.7% Don't forget that all hands are different and if it suits bad, you can use file to adjust the size
