Back in the day before the automobile when this and every other country was run on horse power. The leather punch had to be an indispensable item in every working mans pocket or tool kit. Whether you were on a saddle horse, buggy or driving a team what better combination than a punch and a blade! You could repair most any harness with a HJ and a saddle string and get home.
With all the time, research and money that Charlie has invested in this pattern I think passion is an accurate description. And because he went to Queen with this idea we are talking about it here!

Upnorth had 3 different runs made of the Harness Jack by Queen & 1 made by GEC (but I'll let them discuss that on that forum)
The 1st HJ Charlie had made was on a Teardrop shaped frame. A large Spear point blade & a Cooper punch with half stops. James E. Copper patented this punch in April,1905 & was used by the Robeson Cut Co.
The Teardrop HJ, #042206 was the largest of the 3 HJs Queen made. It is 3 3/4" closed & 6 3/4" AOL with 420 HC steel in both blade & punch. It came with bone handles of 4 different colors, Amber, Golden, Crimson & Mahogany. 100 of each was produced along with 7 "specials" one each of AAA Pearl, Abalone, Tan Bark Mammoth Ivory, Tiger Coral, Ebony, Sambar Stag & Buffalo Horn. This knife was really a big hit here locally, after all it was years since a leather punch & a single blade knife had been seen. I bet I gave away at least 8 of these to local ranchers.
Here is a shot of all the "specials" And the 2 that I was lucky to end up with.
