We have created a 5-piece tool kit [from the perspective of a factory specializing in leather tools] for first-time leather craftspeople.
We selected only the tools that are truly necessary and aimed to create a kit that can be used easily and for a long time.
In selecting kits, we purposely omitted items that could be found at home or easily selected and purchased at home centers, handicraft stores, online retailers, and 100-yen stores.
You can select the pitch (mm) of diamond hole punches.
All five tools are [made in Japan].
They also make great gifts and presents.


【Diamond hole punches①②】
A tool to make holes for hand sewing. Tempered throughout.
Each blade is hand-ground and cut to an exceptional sharpness.
2prongs are used for fine adjustment of corners and drilling.
4prongs are used for drilling long, straight holes.

【Hand sewing divider③】
Used to draw guide lines when punching holes with Diamon hole punches.
Tempered throughout for added strength.
The length of the blade tip is varied so that it does not shift when drawing lines.
Ultra-fine lines can be drawn and accurate holes can be punched with Diamond hole punches.

【Harness Needles M(Round with blunt point)④】
This is a special needle for leather hand stitching.
The tip of the needle is rounded to prevent it from catching when it is inserted into the leather.
Tempered throughout to provide strength and springiness.
It comes in a pack of three, so that there is a spare in case of breakage.

【Cutting boards(OKA Factory Original)⑤】
Used for punching holes with Diamond hole punches and as cutting mats.
The hardness of the cutting boards is matched to the metal hardness of the diamond hole punches, so the cutting edges last longer.
The combination of [Diamond hole punches and cutting board] is important, although it is often surprisingly neglected.
We focused on [size (100mm x 150mm) and thickness (2cm)], which other companies' ¥3000JPY kits do not have.
It can be used for a long time and is stable regardless of the size of the work to be made.
Please refer to the product guide for more detailed explanation of our commitment to this product.
