Multifunctional sapphire. It makes you feel like you're rambo in the woods. Done perfectly. The materials are good, comfortable on the hands, does not slip. Sufficiently massive (~ 1,65 kg). This shovel, baton, cane, axe, pickaxe, saws for wood and metal, ruler, wrench for 14 and 16, knife, screwdriver cross and flat, whistle, spear, the thing for breaking glass, compass (does not work-you need to find such a small format and replace). Could be a fire (i don't have it). Inside the tube will fit many more trifles, will not get wet. Knife base aluminum. I recommend the seller thanks!
