I bought a wave in a first time, I found this one very effective but a bit "soft" in terms of tools. The surge is significantly heavier but much more suitable for daily use in agriculture / logging. It helps to have permanent bases tools, relatively strong self. One should nevertheless not forget that he will not replace a good brand screwdriver "F ..... M" but already allowed me to get me out of hassle when I had nothing on hand, c is the principal. Provide a good belt to wear nice way .... Would recommend
