The grain currently on the market has the advantage of quick availability and a favourable price.
The disadvantage is that after only 10 grains, the palm of the hand shows a very reddened bruise, which hurts so much after 20 grains that the operation has to be interrupted. The graining is often insufficient and has to be regrained.
- quick availability
- No missed kernels (injuries)
- no cramping in the hand
- no dross formation on the centre punch and resulting eye injuries
- simple, accurate striking action
Excellent for training centres and locksmith's shops.
