OKA Diamond Stitching Awl No.2 – 2.5mm

The OKA Diamond Stitching Awl No.2 is a precision Japanese leatherworking awl designed for creating and opening consistent diamond-shaped stitching holes when hand sewing leather.

Made in Japan by OKA Factory, the No.2 features a 2.5 mm wide diamond blade, making it a versatile size for a wide range of hand-stitched leatherwork. It can be used alongside diamond stitching punches and pricking tools to continue, open or refine stitching holes through the complete thickness of the leather.

Unlike a conventional tapered awl, the blade maintains a straight width from the point towards the base, helping to produce a more consistent hole regardless of how deeply the blade passes through the leather.

The hardened tool-steel blade is individually hand-polished for smooth penetration and release, making this a practical choice for traditional saddle stitching and other hand-sewn leatherwork.

    Why Choose the OKA No.2 Stitching Awl?

    The No.2 combines a versatile 2.5 mm diamond blade with the precision and control required for traditional hand stitching.

    The straight blade profile, hardened tool steel, hand-polished finish and careful blade-to-handle alignment distinguish it from a basic general-purpose leather awl.

    For leatherworkers looking to improve the consistency of their hand stitching, it provides a purpose-designed tool for creating, opening and refining individual stitch holes.

    When Is a Stitching Awl Useful?

    A diamond stitching awl is a traditional and versatile tool for hand sewing leather.

    It is particularly useful when:

    • Saddle stitching leather by hand
    • Working with thick leather
    • Sewing several layers together
    • Opening stitching holes through the complete leather stack
    • Following marks established by stitching punches or pricking irons
    • Working where a multi-prong punch cannot easily be used
    • Making individual holes around curves or detailed sections
    • Correcting or reopening an existing stitching hole
    • Carrying a stitching pattern cleanly through multiple layers

    It can be used for wallets, bags, belts, cases, straps, saddlery, sheaths and many other hand-stitched leather projects.

    How to Use

    How to Use the OKA Diamond Stitching Awl

    1. Prepare your stitching line

    Mark your stitching line and establish your stitch spacing using your preferred method, such as a pricking iron or marking wheel (stitch spacer).

    2. Secure the leather

    For traditional saddle stitching, hold the work securely in a stitching pony or stitching clamp.

    3. Position the awl

    Place the point at the marked position or into the existing stitching mark.

    Use the orientation of the wooden handle to help keep the diamond blade consistently aligned with the stitching line.

    4. Pierce the leather

    Push the awl through using controlled pressure until the blade passes sufficiently through the leather.

    The straight-width blade helps maintain a consistent hole rather than progressively enlarging it as the awl penetrates further.

    5. Stitch

    Pass your harness needle and thread through the prepared hole and continue with your normal saddle-stitching technique.

    OKA Diamond Stitching Awl for leathercraft with No.2 Japan on the wooden handle

    Designed for Consistent Stitching Holes

    One of the most useful features of the OKA Stitching Awl is the shape of its blade.

    Traditional tapered awls become progressively wider further up the blade. As a result, pushing the awl further through the leather can enlarge the stitching hole.

    OKA has taken a different approach.

    The No.2 blade has a straight 2.5 mm width, helping the awl create a consistent hole even when it needs to penetrate more deeply through the leather.

    This can be particularly useful when saddle stitching thicker leather or multiple layers, where the awl needs to pass completely through the work without unnecessarily enlarging the stitching hole.

    A Versatile 2.5mm Diamond Blade

    The 2.5 mm diamond blade is a useful general-purpose size for many types of hand-stitched leatherwork.

    It can be used on its own to create individual stitching holes or alongside pricking tools where holes need to be opened or continued through the full thickness of the leather.

    This makes the awl particularly useful when working with:

    • Thicker leather
    • Multiple glued layers
    • Gussets and complex constructions
    • Curved stitching lines
    • Corners and confined areas
    • Individual holes where a multi-prong punch cannot be positioned
    • Stitching holes that require opening immediately before the needle is passed through

    As with any stitching tool, the ideal combination of awl, punch, thread and needle will depend on the leather thickness, stitch spacing and appearance required for the finished project.
