In fifty years of trying gadget pipes with devices to mitigate tongue bite, I’ve found they all work.
The first gadget pipes had stingers. The smoke smacked into the stinger at high speed and a little tar was deposited on the stinger.
Then in the thirties Dr Grabow invented the mass market 6mm filter still used today. It’s a filter. It traps a little tar, a lot of moisture.
Kaywoodie came up with the carburetor in the thirties, a tiny hole in the bottom of the bowl. The later E A Carey and Duncan Hill designs work on the same principle. A tiny bit of cool air is added to the smoke stream. It works.
Savenelli has balsa wood inserts that work like a metal stinger, maybe a bit better.
The metal stem Falcon type pipes use a radiator principle to cool the smoke. So did Churchwardens, by an extra long stem.
My favorite gadget pipes are the 9mm charcoal filter pipes. Since pi r square (and so is cornbread.
) the filtering media and area of a 9mm filter is much more than a 6mm filter. They filter more.
What I didn’t know until recently was the very best way to reduce the pain of puffing is to smoke great big chambered pipes made of the top export grade of Algerian briar before 1954.
If you can learn to love the looks of them, you’ll pull the stingers out of a big Marxman to get more flavor.
An old Algerian briar pipe works to reduce bite because it tastes so good you’ll adapt your cadence to savor it more.
The bigger chamber and thicker walls the better, but they were every one good.
Until November 1, 1954, when the briar pickers in Algeria decided to shoot all the French inspectors instead of picking their briar.
