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
Length : 115mm
Weight : 38g
Material : hard birch wood
I make a leather pouch for fire kit.
My fire start kit is more abundant
But, the wood piston has lower frequency
of ignition than the steel one.
Its tightness of air should be more upgraded.
