Wow, thank you all very much for such a kind words!
Gary there was a range from 1 oz to 9 oz :).
Back of the sheath (part with my logo) is about 9 oz, also as stitch protecting layers inside. Front tooled panel is about 5 oz, and the "frame" on the "face" of the sheath is 4 oz, belt loop is lined with very thin 1 oz layer of leather, skived by hand.
Thanks man, my photography is never ending story of me being not happy with the results . Now I am able to make decent pictures when I go outside about one hour before the sun set . That is the time when pictures come out decent, other times - always something wrong.
Thank you! No, the knife was made by Giedymin KApusciński - polish knife maker, I think you can find him on facebook. Lots of very nice knives in this style, and many others.
