Tandy Leather Craftool Wing Divider — Adjustable Steel Scribing Tool, Knurled Knob & Locking Set Screw

The Tandy Leather Craftool Wing Divider is a durable, adjustable steel scribing tool that locks securely to draw precise stitch lines, borders, and arcs on leather.

Made for leatherworkers who demand clean, repeatable layout marks, this wing divider combines a smooth knurled adjustment knob with a firm set screw to hold measurements steady. Its hardened steel points glide across hides and templates, letting you trace consistent parallel lines, measure buckle distances, or divide curves with confidence. Built for both beginners and seasoned artisans, the tool brings mechanical reliability to every stage of patterning and assembly.

How does the wing divider improve layout accuracy?

The divider minimizes guesswork by providing a stable pair of tips that maintain a fixed distance as you scribe. When the set screw is tightened the arms do not drift, which keeps spacing uniform along long sweeps and tight curves. This reduces rework and helps finished pieces align better at assembly.

• Firm set screw prevents measurement slip while marking
• Knurled knob allows smooth, fine adjustments
• Hardened steel points hold shape for sharp, repeatable lines
• Works on full hides, smaller patches, and templates

Can I use it for stitching lines, borders, and hole spacing?

Yes — the tool is suited for a variety of layout tasks directly relevant to leatherwork. It traces parallel stitch lines, outlines decorative borders, and gauges buckle and hole spacing so hardware lines up precisely. The consistent spacing helps finished seams look professional and balanced.

• Create equally spaced stitch margins on belts and wallets
• Mark parallel decorative borders before tooling or dyeing
• Measure and mark buckle or rivet hole centres accurately
• Divide arcs and complex shapes for symmetrical tooling guides

How easy is it to set and hold a measurement?

Adjustment is quick: loosen the set screw, turn the knurled wheel to the desired span, then lock the screw to secure it. The mechanism resists movement during normal scribing pressure, so once set you can repeat identical marks across multiple components. That predictability speeds up batch work and pattern matching.

• Knurled side knob offers tactile fine-tuning
• Set screw locks the arms for stable repetition
• Durable steel construction tolerates workshop use
• Easy to readjust for different projects or materials

What maintenance does the wing divider need to last?

Keep the tips clean and dry and occasionally lubricate the pivot and screw for smooth operation. If tips become dull, they can be lightly honed to restore crisp scribing. Stored in a dry tool roll or box, this simple maintenance will preserve accuracy and extend the tool's service life.

• Wipe points after use to remove dust and dye
• Light oil on the pivot and set screw every few months
• Hone tips carefully if they lose sharpness
• Store away from moisture to prevent corrosion

Who is this for: The Craftool Wing Divider is ideal for hobbyists learning their first consistent stitch-line layouts, small-batch makers who need repeatable marking fast, and professional leatherworkers who want a compact, dependable measuring device for routine patterning tasks. It’s especially helpful if you value precise margins, even sketching across curves, and the ability to lock an exact width without re-measuring. Add it to a starter kit or keep it in your bench arsenal when accuracy matters.
