Welcome, zoltan,<br><br>We do tend to indulge ourselves a bit on cost, but, as you point out, things are cheaper here, especially relative to the cost of living and most incomes. However, there’s no need to spend a great deal on survival equipment- the basics are available almost anywhere, and should not be expensive.<br><br>I think the needs for an “urban” kit and a “sailing” kit are very different. Looking at your list, for sailing I would quickly add a whistle and a small mirror, both for emergency signaling. I would prefer a small, loud whistle, preferably one without a “pea”, as those sometimes have problems when soaked. Any small mirror will do, it does not have to be one made for signaling, but if it is glass, you must protect it from breaking and protect the back from scratching- duct tape should do well. You might also consider a small compass. I would not want to be on the water without at least that much.<br><br>I would also add needles and strong thread. They cost almost nothing, they weigh almost nothing, but they can keep some inconveniences from becoming emergencies.<br><br>I have not used Esparcia knives, but I gather they are Spanish. I think anywhere in the world you can find knives used in rural areas that are inexpensive and good. Many of the knives marketed in the US that are much more expensive may be a little more convenient to open, and might resist rust more, but they may not sharpen as well or hold an edge as well as simpler knives from other countries. I’m sure there are many fine knives made in Poland and Eastern Europe.<br><br>I own and carry a Leatherman Wave. It is a good piece of equipment, but it is expensive and also quite heavy. I would not hurry to buy one, and be sure that you are prepared to carry that much weight before purchasing it. Most of us find them too heavy to carry comfortably in a trousers pocket. <br><br>I’m sure the others here will have many good suggestions.<br><br>You are to be congratulated- your written English seems excellent.<br>
