Our first thought was that the pin would simply snap off the hammer if we happened catch it on an under-strike. To test this we swung as hard as we could into a 2×4, meeting just the pin on the blow. Nothing happened. We struck the pin until our arms were tired — and even tried whacking the pin on concrete — but the pin didn’t budge. It’ll take a beating.
Trying out the Power Pull with the pin stowed revealed that the Power Pull is, in fact, a hammer. We drove a few 2-1/2” common nails into a 2×4 with no difficulty. The Penntek is weighted and feels just like a normal hammer.
Next we tried out the Power Pull pin. We attached a bit of cord to the end of the hammer through the lanyard hole and attached a fish scale — marked in pounds — to the other end of the cord. We then hooked the hammer under a nail head and pulled the rig back with the pin in the extended position.
The scale read about 18 lbs. for the pull. So we tried a few pulls with the pin in the closed position — like a standard hammer.
As you can see, the result on the scale read 20 lbs. with the pin closed. So on average there was a two pound difference in pulling power required between the pin open and the the pin closed. Sure, that’s almost a 10% difference, but it certainly was below the sense of our “arm dynos” during the test.
Sure, it’s providing some extra leverage, but we’re not so sure it makes a significant difference. We are sure that the extended pin makes positioning the claw a bit awkward. The rounded head on the pin made the hammer wiggle at any change in direction, making it hard to control.
Really, the advantage to the power pull system is the extra inch and a half of length the extended pin provides during the pull. It does make pulling longer nails possible, if a bit awkward.
