Great knife for bushcraft, but the downside is the Kydex sheath, though that’s a downside for Za-Pas Knives. However, Militaria.pl made a mistake: the blade of this knife is 130 mm long (although I'm not sure from which side, I measure it as 120 mm), and the thickness is 4.2 mm. The length of 150 mm and thickness of 4.4 mm is the blade length and thickness of Zapas Knives Expendable, not the Ultra Outdoor.
