Steel Details
Made with high-carbon steel, heat-treated for a hard, sharp edge. Builds character over time and rewards simple care with a knife that keeps getting better.
How Each Knife Is Crafted
Forged Carbon Steel
Every knife starts as a bar of high carbon steel, its roughly shaped then heated in a coal forge and shaped under a power hammer by hand. No CNC, no laser cutting. Each blade is forged individually.
Heat-Treated for Performance
Each blade is differentially heat-treated to bring out the best in the steel. The edge is hardened for sharpness and retention, while the spine stays softer so it flexes under pressure instead of snapping.
Handcrafted Handle
Each handle is carved from rosewood and hand-planed until there are no rigid edges left. Sealed with shellac and glued to the tang, so blade and wood sit as one solid full tang piece. No two handles come out the same.
Sharpened by Hand
Every blade is hand-ground to form the edge, then refined on a whetstone for a polished, clean cut. Ready to use straight out of the box.
Common Questions
Will it rust if I’m using it around saltwater?
Carbon steel and saltwater don’t pretend to be friends. It will patina, and it’ll rust if you put it away wet. Always rinse it in fresh water and dry it properly. Use oil & a sheath to protect it properly. This isn’t a filleting knife that lives in the tackle box. The trade is that it takes and holds a finer edge than any stainless filleting knife at this price.
What size fish is it built for?
The blade is 225mm, which covers most of what you’ll pull out of the water here. Snapper, kahawai, trevally, kingfish. It’s long enough to take a fillet off in one pass, which is what gives you a clean cut rather than a sawed one.
How flexible is the blade?
It’s stiffer than a lot of filleting knives, and plenty of people prefer it that way. There’s still enough give to follow a backbone without it feeling floppy. At 26mm wide and differentially heat treated, the edge is hard while the spine stays softer, so it flexes under pressure instead of snapping. The extra stiffness means it goes where you put it rather than wandering off the bone.
Is it any good for skinning?
Yes. The flex and the thin blade are what you want for getting under the skin and running it along the board. Same qualities that make it good for trimming silverskin off meat if you’re not cooking fish that week.
Can I use it for anything other than fish?
It’s not a chopping knife, so don’t reach for it to do onions. But a long thin flexible blade slices cooked meat beautifully and trims better than most things in the drawer. Plenty of people buy it for fish and end up using it on a roast.
