Maybe I can send them a message about getting a 24" loop. Some guys are wanting to do a chain race this spring/summer

couldn't hurt Mike, I'm always up for a good race. Would be interesting to find out how the new chain compares to stock LGX/RSC. And how that compares to square OEM Chain. That gives us a good baseline for all the competitors who do their own square file/grinding.

Yep. Be interesting. Probably run it on a 372 xpw or 385. Poplar or white pine cants

New sawchain design has come and gone over the decades.
Here's a interesting one from January 1970 issue of Chainsaw Age magazine.
Looks quite revolutionary but this was the only ad of this chain as it and its company disappeared from the face of the earth forever.

With some research this chain was originally built by a couple of partners who set up a chain plant in the late 1960's near Victoria B.C. Canada but they  quickly went out of business and sold the plant to Windsor.
They moved to California with different partners and design then took a another stab at it.
Maybe someone bought them and the patent out?

Oops a little miss information fellas. I've been doing lots of research and posting on different saw sites over the years and my short term memory for me is not what it used to be. Haha.
The Victoria BC Canada chain plant was not the origins of the Kerf Splitter sawchain. But was the origins of Doug Lemery's Atlas chain which then became the Kolve chain of the 1970's-'80's.
Notice the 1966 article's #3 pic of the chain hardening equipment in Lemery's plant then the same equipment in Windsor's pic in 1971.

Here's the only other article of the Kerf Splitter chain I can find and also the chains patent download with 2 illustrations near the top.
Interesting thing was the K&S chain was originally patented in 1946 same year as Joe Cox's Oregon Omark chain.
Then the K&S was repatented in 1962.

That is so cool that you could find those old articles.
