Wood fire piston


It is growing hotter day by day.
Thus I am idle by day and work by night.
A electric shock bug killer
is packed with bugs.




I make two fire pistons,
the one is made by steel,
the other wood.
The steel piston is made
for calculating sizes of
wood piston.





Length : 115mm
Weight : 38g
Material : hard birch wood




I make a leather pouch for fire kit.
My fire start kit is more abundant
than before.




But, the wood piston has lower frequency
of ignition than the steel one.
Its tightness of air should be more upgraded.

  1. I know you've shown it before, but I like that knife! I've never tried a fire piston.

  2. Thanks your favorable comments! I sharpen pencils, open boxes, cut boughs, dig out weeds by this knife. :) Fire piston is a wise tool of Malay and austral-asia.
