Enjoying my reknotted Mohawk 5-341 today ...
I don't actually recall what the original knot was, but it was pulled and I managed to secure a large (well, large at the time at 22mm IIRC) PurTech synthetic knot. Again, at the time, any synthetic let alone a choice of synthetic was a scarce thing, but one or two Chinese eBayers were starting to move PurTech.
The manufacturer of PurTech clearly had Muhle Silvertip Fibre in its sights and almost made it! It's a superb synthetic, good backbone without being flicky, flows well, hydrates lather well without dumping all the water in one go and one the face it has just a bit of scritch.
The knot it but one half of a brush ...
The handle is a glorious Art Deco-styled piece, standing reasonably talll amongst its peers, akin to the older "professional" style like the Ever Ready to its right.
Another shot?
Of course, you might well recognise this shape ...
PAA found the expired patent and re-released it as the Starcraft. Nice, but not a patch on the original.
