In Use


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.

    I would never have considered using it with the pin extended to begin pulling any nail. It seems obvious to me that this pin is designed to enable pulling a long nail *without* having to search for a bit of wood to use as a fulcrum. If I was still in the construction industry I’d buy one.

    At a young age, my dad taught me to use a piece of scrap wood to assist with removing stubborn nails. In high school I was a scrawny kid. My friend Will was a star football player and wrestler. While working together on a homecoming project, Will was trying with all of his might to remove some nails from on old board we found in the barn. I grabed a hammer and piece of wood and easily pulled them all out. It was a classic case of brains over brawn. But unlike the Hollywood movies, he still got the date with the cheerleader.

  3. I hate to use a cheesy play on words but Brau “nailed it on the head”. The PowerPull™ works best after a long nail has been partially pulled (and probably not when starting to pull a nail). It’s that block of wood you need built right into the hammer.

    The claim about increasing leverage is probably best seen in our quick test video on our site (link below). The test simulates pulling a long nail with a digital force gauge, which is set to show the peak force. You’ll see we get 223 lbs. without the pin and 490 lbs. with the pin extended. There is a point when pulling a nail (about 2″ to 2.5″) that a rip hammer starts to lift off the board…this is when you lose leverage and it then comes down to brute force. With the pin extended the leverage point is again moved close to the nail head resulting in much higher leverage (2x – 3x).
