My 20mm silvertip knot came unglued from my 1915 ever-ready handle; I had epoxied it to the sides of the hole since the knot itself was too big to allow it to fit all the way down. I just ordered a new 18mm Best knot, but in the meantime, does anyone know sizes of vintage or modern handles? I'm more into function than form for this one - I'd like something waterproof and have no problem with a cheap drugstore boar brush for a handle, but was wondering if anyone knew opening sizes for other handles?
