Sweet, and it doesn't throw the blade away! I wonder if it's "valveless" too... also, typical Russians not caring about water spilling on their wooden floor :roll:

Made a cover the handle, still need cut the groves out to look more like the real one. Then some black paint and its done.

I also ground the first 2cm of the blade about 1mm thiner and it made a big improvement in penetration of the same wood as before this time is just poked through 2 cm of pine, didn't get pics just yet be will asap.
