The Silca website showed a claimed weight of 170 grams. I weighed it when I got it and it was 386 grams, more than twice the claimed weight. Even without the separate piece it is 270 grams and without that you have no chain breaker or disc spreader. It is a poor design with two separate pieces that donï¿½t really fit together other than some tiny magnet that kind of holds them together. I bought to replace a Lenzye multi tool that actually weighs more so the Silca is going back. I now will no longer believe any claimed weight of Silca multi tools.
