Zoltan,<br><br>Welcome to the forum. Your English is fine. Don't apologize for it. Besides you are fluent in at least 1 more language than most of us.<br><br>We are prone to getting a lot of equipment & it can become expensive. But it is all useful. And don't forget: the only difference between men & boys is the price of their toys.<br><br>I like Leatherman tools a lot. The Wave has the best ergonomics. It can also adequately substitute for a pocket knife. As a small tool kit, the older & much cheaper Supertool is much better for my purposes. I have both. The Supertool pliers can be opened wider: 23 vs. 27 mm. at the inner, wide, concave section of the jaws. I have found it more useful for work relating to plumbing (e.g., faucet cap, Coleman fuel cap). The Supertool also includes an awl, crimper, and ruler 21 cm. long, and slightly longer screwdriver blades & handle. The Wave has knife blades which can be opened with 1 hand, scissors, & 1 more flat screwdriver blade than the Supertool. The Supertool is about 1 ounce heaver than the Wave, and both are a little heavy for pocket carry. My comments are based on my older, original model of the Supertool, not the newer version which I do not have. If I had to choose between the 2, I'd go for the Supertool. The Supertool is nominally priced about 3/4 the price of a wave. Sometimes, they sell for a lot less than that. Note, however, that I have given both my older son & wife the Wave as presents. I normally carry a Victorinox Huntsman pocket knife which has scissors. Their pocket knives do not have scissors. You may find a much better deal on a Supertool than a Wave. Alternatively, the Victorinox multitool was considered favorably by Doug Ritter in his review this website. Conceivably importing into Poland from Switzerland might be cheaper than from the USA.<br><br>When I took my sons shooting earlier this afternoon, they used our gun club's target rifles. In helping the boys evaluate the targets for zeroing the sights, I missed the ruler on my Supertool since I had only a Wave. I normally leave my Supertool in BOB, & carry the Wave, except on outdoor trips. One nice thing about using the gun club's equipment is I don't need to carry or clean ours. :-) And the boys get to learn cleaning on the club's guns rather than ours. :-))<br><br>Good luck, <br><br>John
