Thank you, Michele Molletta for your M4 knives in M390, they are among my favorites.
Aftermarket kydex sheets for my M4 knives would make my happiness even more complete
Although I am a fan of smaller knives from 8 to 10 cm, the T6 in K490 has become my first big knife, I am very happy with it.
I already dream of the T8 or T10 made the same as the current T6, just to have it. You never know in case of a zombie acopalyps...
For what it's worth the Bradford 3.5 with 8cm blade in M390 steel is also one of my favorites, because it is a light weight, and is just great enough to accomplish most backpacking tasks. Maybe a good idea for a new design?
With many thanks, and greetings,
Johan
edit: Maybe a double-sided pocket diamond sharper of 12cm by 4cm is a good idea, 600 and 1000 or 1200 grit self-adhesive on an aluminum or titanium plate of 3mm, to stay light weight .
I love M390 because I hardly ever have to grind it in the outdoors.
