GR Pro Secateurs / Niwaki
The GR Pro is Niwaki's best-selling secateur, hand-forged in Yamagata in northern Japan and built around Japanese steel rather than convenience. The blade is KA70 carbon steel, which takes and holds a notably keen edge but will stain and eventually rust without care, the trade most Japanese cutting tools make for sharpness. It is a bypass secateur with a strong spring, a chunky safety catch at the base that flicks closed one-handed, and removable yellow vinyl grips, the detail that gives the 'double yellows' their name and makes them easy to find in a border. The grips pull off for a plainer look. It suits gardeners who will clean, oil and sharpen a tool in exchange for an edge ordinary stainless secateurs cannot match.
Design intent
- +Choosing KA70 carbon steel over stainless is the defining decision: it buys a harder, sharper, longer-holding edge in exchange for maintenance, which is the priority a working tool is built around.
- +The bright yellow grips and base-mounted safety catch are practical choices, making the tool visible when dropped in foliage and lockable with one hand without setting it down.
Trade-offs
- -Carbon steel stains and rusts if left wet or dirty and is more brittle than stainless, so it chips if used on wire, stone or thick knotted wood.
- -It is a precision pruning tool, not a lopper: cutting beyond its rated diameter strains the blade and the joint and is better handed to a saw.
