Twin Diamond File
Twin Diamond File
For the tools that have seen better days—and the gardeners who refuse to give up on them. The Niwaki Twin Diamond File is the ultimate intervention for blades that have lost their way.
This isn't about a light touch; this is about restoration. With two sides of electroplated diamond at your disposal, you’re equipped to handle the heavy lifting. The #120 side is the workhorse, designed to eat through steel and reset an edge that’s long since vanished. Once you’ve reclaimed the shape, flip it over to the #300 side to provide a finish that’s ready for the final polish. No water required—this is a strictly dry affair.
Invaluable for fixing damaged blades or giving rougher edges, like those on your mower, some much-needed discipline. Made in Japan with the kind of precision we live for, it’s a 50g powerhouse that fits perfectly into any tool-care ritual.
Made in Japan
Pro tip: Once you’ve reset the edge, move over to a #1000 grit whetstone to finish the job. Your blades will thank you, and your hedges will notice the difference.

“I wish I had discovered this years ago. Made the perfect gift for the man who ‘has it all’. Beautifully crafted, I was pleasantly surprised how heavy and sharp it was. Would buy again.”

“I love the easy access both sides, the height was sufficient to grown runner beans on a tall mesh frame and it’s very easy to put together but may need two people to lift the net over the framework. Just love it.”

“I have one and it is a game changer. Enough pockets to totally fit all the tools I wanted to carry. It's great to have them all in one handy place when I'm working in the garden instead of floating around in the bottom of the wheelbarrow.”

“Where has this tool been all my life? It is awesome, works brilliantly, even with older dried out flax. Literally like a hot knife through butter."
