{"product_id":"zen-wu-f-4-hammer-titanium","title":"Zen-Wu F-4 Hammer (Titanium)","description":"\u003cp\u003eThe Zen-Wu F-4 is a steel-faced woodworking hammer and the successor to the F-1. It pairs a hardened stainless steel strike face with a TC4 titanium body, joined by a brass ring at the seam.\u003c\/p\u003e\u003cp\u003eTitanium sends less recoil back to your wrist than steel and puts more of your swing into the work, instead of losing it to flex and vibration. The opposite end of the head is slightly convex, ideal for kigoroshi (compressing wood fibers so a joint swells tight) and other shaping work.\u003c\/p\u003e\u003cp\u003eThe handle is dyed hickory, with its open grain filled with brass powder.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStrike face: S136 ESR stainless steel, 52-53 HRC\u003c\/li\u003e\n\u003cli\u003eBody: TC4 titanium\u003c\/li\u003e\n\u003cli\u003eHandle: dyed hickory, brass powder grain fill\u003c\/li\u003e\n\u003cli\u003eHead size: 2-13\/16\" x 1-3\/4\" (70.9 x 44.3mm)\u003c\/li\u003e\n\u003cli\u003eOverall length: 11-5\/8\" (295mm)\u003c\/li\u003e\n\u003cli\u003eHead weight: 16 oz (450g)\u003c\/li\u003e\n\u003cli\u003eTotal weight: 20 oz (560g)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eJonathan's Hot Take\u003c\/h3\u003e\u003cp\u003eZen-Wu took everything I loved about their F-2 and kept pushing. You get a hardened stainless face for driving chisels and a titanium body that soaks up the shock, so you can hit hard all day without your wrist paying for it.\u003c\/p\u003e\u003cp\u003eThe convex back end is a sneaky great feature. Kigoroshi is an old Japanese joinery trick where you bruise the fibers of a tenon so it slides into the mortise, then swells back up for a rock-solid fit. This hammer is built for it.\u003c\/p\u003e\u003cp\u003eAnd look at that handle. Dyed hickory with brass packed into the grain. It's a tool that looks like jewelry and works like a workhorse. Another perfect gift for the woodworker who has everything.\u003c\/p\u003e\u003cp\u003eThose titanium wedges make me smile every time I hold it and it really just fits perfectly in your hand.\u003c\/p\u003e","brand":"Zen-Wu Toolworks","offers":[{"title":"Default Title","offer_id":67772207300778,"sku":"F4T","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/6358\/3402\/files\/zen-wu-f-4-hammer-titanium-01.jpg?v=1793221454","url":"https:\/\/kmtools.com\/products\/zen-wu-f-4-hammer-titanium","provider":"KM Tools","version":"1.0","type":"link"}
