At Spring Tools, we create tools based on this principal. Our tools are about the size of a ball point pen yet have over 3500 lbs of striking impact and use no other outside force such as a hammer. Simple is good: The Spring Tool concept is designed to re-direct energy in a very concentrated area between (2) very strong carbon steel pieces that are permanently connected by a spring made out of high tensile strength music wire. So good that we guarantee our nail sets \u0026amp; center punches to be the best in the world. Easy to Use: Energy can be released in very small finessed tapping motions on precision work surfaces such as fine wood. Longer pulls can deliver a whopping impact that can drive a large box nail through a piece of lumber or center punch through cold rolled steel. The Old Way: All Spring Tool products are made with industrial grade materials and have been designed for the professional tool user. Our tools are designed and made in the U.S.A.        \u003c\/div\u003e","brand":"Spring Tools","offers":[{"title":"Default Title","offer_id":53777680662856,"sku":"B000FK3W0K","price":37.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/0463\/1880\/files\/horoshop-f195362ae0f0.jpg?v=1786700208","url":"https:\/\/sigonnatools.com\/products\/spring-tools-professional-high-speed-steel-center-punch-marks-hardened-steel-hardox-450-true-tempered-tip-3500-lbs-impact-force-made-in-usa","provider":"SIGONNA Tools","version":"1.0","type":"link"}
