The problem with hard ground is that it takes a bit of persuading to get your banksticks into it, and the use of a metal hammer only damages the top of the bankstick. Well this little fella allows you to beat the stuffing out of your sticks without damaging threads or burring bankstick outers. Simply insert into thread or outer and bash away. Simple but dead handy!
Strong aluminium construction. Fits into the top of most banksticks.
