As a carpenter for the last 16 years...
I have first hand experience with the frustration of the waffle on a brand new framing nail driver wearing smooth long before the rest of the nail driver wears out. As anyone who swings a nail driver for a living knows, that grooved surface makes all the difference in driving nails. That same surface, though, damages finished products, and can make mincemeat out of fingers or thumbs that get in the way every now and then.
For over a decade and a half, I dealt with the aggravation of using a nail driver that just did not hold up under every day use. Worse yet, when titanium nail drivers became available, the problem was all the more troublesome because the cost of those nail drivers was so much greater, while the traction lasted only a fraction of the time that a steel waffle did, which was only a few months at best. It was then that my brother had an idea: place a hardened steel disc with the waffle formed in it into a cavity bored in the face of the nail driver, recessed slightly from the smooth outer rim. This protected the waffle from ever coming into contact with anything but the nail being driven, no matter what material the nail was being driven into. At the same time, it also protects fingers from those merciless sharp points on a brand new waffle. His idea worked.
The result was the best framing nail driver either of us had ever seen. Now the waffled face lasts longer than the rest of the nail driverr, and we no longer have to switch to a smoothed face nail driver for finish work. We wore out three hickory handles over the course of 18 months, and the first nail driver we made still looks like it has only been used for a few weeks. The level of abuse this nail driver received and survived was astounding. We quickly saw that we needed to get this nail driver out there, so we patented it and decided to start a company dedicated to making a nail driver that outperforms all others.
After all, pro carpenters work hard; shouldn't our #1 tool be able to keep up? Finally, there's one that can. As my brother said after a hard day?s framing ?This nail driver is HARDCORE! And it has one, too...?
