Hi JD Spydo. Thanx for the interest.
The original Dyad concept was two fold. The first was a two bladed folder with dual nested Walker linerlocks. G-10 scales. Nice piece. There are a few prototypes floating arond.
The 2nd was a center liner with two Walker linerlocks coming out of the center liner on each end. Two blades with large pivots, and no scales.
For one reason or another, our factory manager at the time, was not able to get the first one into production and never made the prototype of the second version.
In an effort to get the model into production, we made the smaller Dyad as a lockback in Seki-City, Japan. Our Seki makers were still learning linerlocks at the time, so a lockback was easier to make for them. The first version had micarta scales and a clip. Probably about 1200 of those around.
Peter Jhones in our R&D dept invented the "by-pass" lock which was put on the larger version, with micarta scales and the smaller FRN version. The by-pass lock was quite ingenious and would permit a stronger lock.
We made about 1200 of the large variation. The FRN version also had small runs in colors in addition to the black piece.
About that time, the "Kiss" model from CRKT came out, so we abandoned the concept of the two bladed/ single center scale version.
Then another larger knife company made a "less expensive Chinese copy" of both models of the Dyad in FRN. We tried to stop them legally. After all, we had 3 patents and 2 trademarks on the designs, but we lost. "LLD" (lawyers, loopholes & Dollars). They told the judge something about "teaching Sal a lesson".
They certainly did.
We couldn't compete with the "less expensive" version, so we disco'd the pair.
I should add that I have a double bolstered jigged bone version of the mini and I have an even smaller double bolstered jigged bone version. Both concept models that we showed at shows but didn't get a big response. I carry them quite often. No clip. Neat little pocket pieces.
