PRODUCT OVERVIEW ========== --\u003e\n\u003ch2\u003e🔨 Product Overview\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eWhite Steel Diamond Chisel Set\u003c\/strong\u003e is a professional punching tool for hand sewing leather goods. Made from genuine HRC62 white steel (not common stainless iron), these chisels create clean, evenly spaced diamond-shaped holes that are essential for saddle stitching. The upgraded thick version features a handle width increased from 5.7mm to 8.6mm, providing better grip and control. Available in four spacing options (3mm, 4mm, 5mm, 6mm) and four tooth counts (1, 2, 4, 6), you can choose individual chisels or complete sets (1+2+4+6 teeth per spacing).\u003c\/p\u003e\n\u003cp\u003eWhether you are making a small wallet (3‑4mm spacing), a handbag (4‑5mm spacing), or a heavy saddle (6mm spacing), these diamond chisels deliver precise, consistent holes without tearing the leather. The chisels are heat‑treated to HRC62 hardness, offering excellent wear resistance and edge retention. Each set also includes a free multi‑function puller (or chopper) to help remove chisels from dense leather safely. For best results, use with a soft cutting board (not a hard punching board) and strike vertically to prevent breakage.\u003c\/p\u003e\n\u003c!-- ========== 2.

For corners or curves, use 1‑tooth or 2‑tooth. Match spacing to your project (3mm for fine, 4mm standard, 5‑6mm for heavy).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMark your stitch line\u003c\/strong\u003e – Use a wing divider or stitching groover to mark a line 3‑5mm from the leather edge. Align the chisel teeth along this line.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition the chisel vertically\u003c\/strong\u003e – Hold the chisel perpendicular to the leather surface. Striking at an angle will break the teeth. Use a mallet (rawhide or poly) – avoid metal hammers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrike with even force\u003c\/strong\u003e – Start with light taps to set the teeth, then strike firmly until the teeth just penetrate through the leather. Do not drive the chisel deep into the cutting board – only enough to exit the leather.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemove the chisel\u003c\/strong\u003e – Gently rock the chisel side to side to loosen, then pull straight up. If stuck, use the included puller: hook it under the chisel head and tap upward with a mallet. Never pull at an angle or use pliers on the teeth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinue along the seam\u003c\/strong\u003e – Insert the first tooth of the next strike into the last hole of the previous strike to maintain even spacing.

FREQUENTLY ASKED QUESTIONS ========== --\u003e\n\u003ch2\u003e❓ Frequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: What is the difference between white steel and stainless iron chisels?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: White steel (HRC62) is much harder and holds a sharp edge longer than common stainless iron (typically HRC45‑50). White steel resists dulling when punching thick leather, but it is also more brittle – you must strike vertically and avoid prying.\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: Which spacing should I choose for a beginner making wallets?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: 4mm spacing is the most common and recommended for beginners. It works well with 0.45‑0.60mm thread and gives a classic stitch look. A 4‑tooth chisel is ideal for straight lines, plus a 1‑tooth for corners.\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: Do I need to buy the full set (1+2+4+6 teeth) or can I start with just one?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: You can start with a 4‑tooth chisel and a 1‑tooth chisel (for corners). However, the full set (1+2+4+6) is more convenient for long seams (6‑tooth saves time) and curves (2‑tooth is easier than 4‑tooth). The free puller with the set is also very useful.\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: Why are my chisel teeth breaking?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: Most breakage occurs from striking at an angle (not vertical) or prying the chisel out sideways. Always hold the chisel perpendicular to the leather. If stuck, use the puller to lift straight up. Also, never punch on a hard surface – use a soft cutting board.\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: Can I use these chisels on chrome‑tanned leather?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: Yes, but chrome‑tan is softer and more elastic. The holes may close up slightly after punching, making threading harder. For best results, use a slightly larger spacing (4‑5mm) and wipe the chisel teeth with wax or soap before each strike.\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: How do I maintain and store the chisels to prevent rust?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: After each use, wipe the teeth with a dry cloth. Apply a light coat of machine oil or salad oil to the steel parts. Store in a dry place. Avoid leaving them on damp leather or in humid environments.\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-question\"\u003eQ: What is the free puller\/chopper used for?\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-answer\"\u003eA: The multi‑function puller helps remove chisels that become stuck in thick leather. Hook it under the chisel head and tap upward with a mallet. It also acts as a chopper for cutting thread or small leather pieces (depending on the model).\u003c\/div\u003e\n\u003c!-- ========== 8.
