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
