01 / SUSTAINABLE
Basic version: machined on one side, no shaping
This is the basic version of the WKidea wooden-handle utility knife. On the regular models the wood covers are cut into a shape; on the basic version the cover is machined on one side only and stays flat, with no shaping. That is why it is part of our Sustainable Picks, offered at a lower price.
Specifically: the body is an SDI 0439C, whose auto-lock SDI rates to withstand up to 8 kg of force; the cover is domestic Taiwan hinoki, it comes in a black paper box and ships from stock in 2–3 business days. Overall it measures about 145 × 25 × 10 mm and weighs about 25 g, including the knife body and the wooden cover.

Basic version look
• The wood cover is machined on one side only and stays flat, with no shaping, unlike the shaped handles of the regular models.
• The body is the same original SDI 0439C, and the wood is the same domestic Taiwan hinoki.
02 / MATERIAL
Domestic Taiwan hinoki cover
Taiwan hinoki carries its natural scent and fine grain.
About the grain
• Each handle comes from a different piece of wood; differences come from the sawing direction (quarter-sawn / flat-sawn), growth ring width, and whether it was cut from heartwood or sapwood.
• Knots and grain variation are features of natural wood, not defects; product photos show actual pieces for reference.
03 / CRAFT
CNC-machined on one side
WKidea uses only CNC subtractive machining, cutting the cover from a solid block of wood, with no injection molding. The basic version is machined on one side only, with no shaping cuts.
04 / HOW TO USE
How to use
01 Push the slider on the body to extend the blade, only as far as you need.

03 When the blade gets dull, buy SDI 1361 or K361 replacement blades.
04 When not in use, store it in the black paper box.
Blades and replacements

05 / CARE
Simple natural beeswax care
Retract the blade before care:

03 Avoid soaking it in water or leaving it in direct sunlight for long periods.
Beeswax for care: WKidea natural beeswax. Avoid long sun exposure and humid storage.
