Recently the ReUse was contacted by Nail Jack Tools LLC to alert woodworkers, especially reclaimed wood workers, about their new nail pulling tools, the “Nail Hunter” and “Nail Jack”. Nail Jack Tools very kindly sent us a set of these tools to evaluate and since the weather was pleasant yesterday I decided to take the Nail Jack out into the yard to de-nail a pile of lumber from a recent deconstruction job.

The Nail Jack and the Nail Hunter are functionally identical tools, except that the Nail Jack is Larger. Since building deconstruction literally produces tons of lumber studded with nails ranging from 10 inch long spikes to carpet tacks, I decided to use the larger Nail Jack, figuring that it could pull the largest nails but could probably extract any smaller nails as well.
The pile of lumber I de-nailed is a daunting opponent for any nail pulling tool as it consists of a



stack of, mostly 8×8 oak timbers recovered from a 100-year old barn. Typical to old barns, overly large nails were used in its construction, many 8 gauge or larger. Additionally many of the beams bristled with an assortment of smaller nails, cut nails, tacks, and staples used for cross beams, wiring, siding etc… Many of the smaller nails were heavily rusted, bent and embedded into the wood.
Before detailing my reasons I’ll get right to the ending – I think the Nail Jack is a really great and useful tool. It is innovative, seems well built, hardy, and very reasonably priced for contractors and do-it-yourselfers, at about $25 a tool (nippers, $15-$40 depending on quality).
An initial reaction by my colleagues was a “So what, it’s a glorified pair of wire cutters or nippers”. But it isn’t, and only after you start using it does its thoughtful design and utility become apparent.
First, there are the two sets of jaws, beaked jaws in the front and the grooved jaws in the rear
that can grab onto nails at any point along the shaft. The narrow internal width of the beaked jaws allows the user to clinch the nail with significant force. Thus the nails do not need an intact head to extract them, just a small exposed piece to affix the jaws onto. The rear jaws are wider and primarily grasp exposed nails, especially large ones, between a set of three teeth so that substantial pulling force can be generated. What sets the Nail Jack apart from a pair of nail nippers is the banana shaped head that allows the user to leverage nails from almost any angle; backward, rolling side to side, or pushing forward when the rear jaws are used. The rear jaws also double a strike plate to hit with a hammer to bring extra force to the
nail. I must confess I did not need this as its pulling ability was more than sufficient for the nails I encountered.
The tool’s features clearly sped the work because I could quickly re-adjust the tool back to the starting position to keep maximum force on the nail without having to use wood blocks to increase leverage or switch to tools for different nails or difficult situations. I should also mention that I alternatively used the nail jack with one or two hands and pulled or pushed depending on the situation.
An additional advantage I noticed while de-nailing timbers (as opposed to narrower boards) is that the range of motion of pulling is so wide that I could pull nails relatively easily on the top and sides of the timbers. This necessitated less moving or rolling of the lumber over, making the job easier and faster.
Since you can grip the nail at any place along its length and quickly re-adjust the tool back to where it has maximum leverage, each extraction consists of a sequence of small pulls rather than one long pull. Thus the tool spends more time flat against the wood, spreading the pulling force more widely and causing less damage to the wood. I generally noticed that even gnarly and crooked nails left with holes not much larger than the width of the nail.
In the approximately two hours I spent pulling a few pounds of nails with the Nail Jack I only resorted twice to using a pry bar and the nippers. I required the leverage of the nippers to pull a particularly long (~8 inches, upper right corner of photo) and crooked nail. To be fair this nail barely fit in the jaws.
The one downside I encountered with the Nail Jack is that there is a
spring that pops the tool open as the default state. This spring, located in the rear jaws seems somewhat vulnerable to damage. In fact the spring in our tool developed a kink (last photo) after I used the rear jaws to push out an 8 gauge nail. I believe the force of the nail head pressed against the spring damaged it (it got the nail out though). Despite the kink the spring is still functioning but I believe it will succumb to metal fatigue relatively soon. We have contacted Nail Jack Tools and it appears that the spring can be easily replaced or used without it. I personally liked the spring loaded action as it readied the tool quickly for the next pull.
So in conclusion I highly recommend the Nail Jack. I believe that home renovators or re-used material carpenters will find this tool very useful. I also believe that the spring may not be a big issue for lighter duty jobs. The Buffalo ReUse is particularly hard on tools and, all in all, I thought this tool did an excellent job and fared well under tough conditions.
