M390 Curved Leather Trimming Knife for Small Radius Cuts
💐Product Highlights
This curved leather trimming knife is made for leathercrafters who need more control in tight curves, hollow areas, and detailed cut work. It uses factory heat-treated Bohler M390 powder steel, so the blade starts with a strong hardness level and stable edge performance, instead of relying on post-machining heat treatment that can be inconsistent. If you often cut small curves, trim corners, or want cleaner details than a standard utility knife or straight leather knife can give, this is the kind of tool that makes the work feel easier and more precise.
Key Features
-
Factory heat-treated Bohler M390 powder steel
Made from Austrian Bohler M390 steel with a stable heat treatment and deep cryogenic process. This gives the blade strong wear resistance, corrosion resistance, and solid edge retention for detailed leatherwork. -
Hardness: HRC 60–62
A practical hardness range for users who want a blade that stays sharp longer while still being suitable for precision hand use. -
Single-bevel, hand-ground V edge
The blade is finished with a single-bevel V grind, making it better suited for controlled trimming and detail cutting, especially when following small curves. -
Better for small curves and hollow cuts
Designed for small-radius curve cutting, inside curves, and finer trimming work. It helps achieve details that are harder to get with a standard leather knife or craft knife. -
Clean, precise trimming for detailed work
Useful for pattern trimming, corner cleanup, curved edges, and other precise leather cutting tasks where control matters more than speed. -
Premium handle materials
Fitted with a purple sandalwood handle and H62 brass ferrule / guard material, giving the knife a solid feel in hand and a clean, classic look on the bench.

Who It’s For
-
Leathercrafters who cut small curves, inside curves, and detailed shapes
-
Makers who want a knife with better edge retention and corrosion resistance
-
Users looking for a fine trimming knife for detail work rather than a general-purpose cutter
-
Anyone who wants a more specialized blade for work that standard straight knives do not handle as neatly
Why This Steel Matters
A lot of leather knives on the market are cut first from softer steel and heat-treated later. In practice, that can lead to uneven results depending on the heat treatment process and batch size. This knife takes a different route by using already heat-treated hard steel as the starting material, helping preserve the performance potential of the steel itself. For a tool like this, the steel and heat treatment are a big part of what makes the edge feel reliable over time.

少し高い買い物でしたが大変満足しています。
ありがとうございました。
This was my first custom made cutting die, went for clear acrylic which is absolutely great so much easier to use and less mistakes which means less wastage, the cutter all works great and am looking at another couple of designs that I will be sending them to quote and probably make.
for our small business in austria, we ordered the maxita ec 27 machine with full accessories from ciofficial, and honestly – this turned out to be one of the best business decisions we’ve made.
from the very first contact, their team showed exceptional professionalism, speed, and genuine willingness to help. communication was clear, friendly, and always responsive – every question was answered quickly and precisely.
after placing the order, we immediately received a tracking number and were able to follow every step of the shipment. the entire delivery process was transparent and perfectly organized.
when the machine arrived, the packaging truly impressed us – extremely solid, professionally designed, and perfectly protecting both the machine and all accessories. it was clear that great care and attention to detail went into every part of the packaging.
and then the machine itself – simply a wow moment. the build quality is outstanding. every single part and accessory is precisely manufactured, solid, and clearly made to last. we honestly couldn’t find this level of quality on the austrian market.
ciofficial is not just a machine supplier, but a true business partner. a huge thank you to the entire team for the excellent support, quality, and professionalism. highly recommended to anyone looking for the best – without compromise.
Machine reçu dans un colis super bien emballé.
Des matériaux de qualités, c'est beau et ça a l'air solide.
Facile d'utilisation et bien pensé.
Service client réactif et super aimable pour toutes vos questions.
Je suis très contente !
J'ai un gros a priori à commander en Chine !
Car il y a beaucoup d'arnaques et ça fait peur !
Mais le fait de pouvoir payer avec Klarna m'a rassurée, je savais qu'en cas de problème ils m'aideraient.
Mais tout s'est très bien passé !
Délais respectés, pas de taxe ou douane supplémentaire, et alors la machine est magnifique.
La finition et les matériaux sont de toute beauté.
Facile à mettre en route malgré le mode d'emploi en anglais et chinois. J'ai déjà eu contact avec le service pour des tampons personnalisés.
Je rajouterai un commentaire pour vous en dire plus quand je les aurai !
Ah oui, le réglage du laser... "la patience est une vertu."
Mais je suis vraiment ravie, c'est une belle machine.
🤗🤗🤗🤩
I have had several stitching ponies and stitching horses. By far this is the best I have ever used. The strength of the device far exceeds anything used before. I've used it for several projects and seen no movement anywhere, while pulling tough needles through heavy leather. "10 out of 10"
absolutely beautiful.
I bought these large capital letters for customization with initials.
They are very legible and have a nice size. I am very happy with the set also containing spacers and special characters. Would recommend.
Well built. Above-average engineering. No cheap parts. I have the walnut base, and it is in perfect condition. The shipping container is built specifically for the item so that it does not move around in the box.
I am new to leather work and had a cheaper pony from Amazon - it did the job but as I progressed, I realized that I needed something a lot better. This pony is just exceptional - the craftsmanship is second to none and the range of adjustments is just incredible. I love sewing with this and actually get excited ha ha.
Excellent and Outstanding Service.
The EC17 is a piece of art. I am sure it will bring my brand and projects to the high level I want.
Thank you.
I am very happy with my purchase of the Maxita EC-17 from Ci Official. The package arrived well packaged and thoughtfully packed, including extras (e.g., a really good tool for the machine and high-quality tweezers for the letters, and even extra screws to use with my existing typeface).
Ci Official's customer service was outstanding. I had a few questions in advance, which were answered quickly and in detail. I also accidentally selected the EC-27 positioning caliper, but this was immediately pointed out to me and the correct one was sent to me separately at no additional shipping cost.
I will be making further purchases from Ci Official.
Very quick delivery to UK, and a product that is even better on the bench than I could have hoped for.
Having seen Robert Little recommending this pony I took the plunge. I AM DELIGHTED
Well I was a bit sceptic due to made in China products well I Was so wrong. The pony and the arm are top quality. Extremely well build and outstanding customer service.
I am fairly new go leather crafting. My first pony was cheap and so frustrating I rsrely used it. Then I stumbled on a review of this and bought it. It's perfect. Flexible in how it can be mounted. Flexible in the way the clamp can swivel means you can position your work piece exactly where you want it.
It really is a brilliant design. No regrets buhing this.
