Description
Small Bushcraft – O1 Tool Steel with Firesteel
This knife was inspired by the Condor Bushcraft Knife and the Bark River Bushcraft knife. My version has a thicker blade than the Condor and is a little bigger than the Bark River. It is a tough Knife as it is made with O1 Tool Steel.
The blade is approximately 4.3mm thick and is 3.8 inches (98mm) long. It has been heat treated to 61.2 Rockwell by Ausmaker Supplies in Sydney. The spine has been ground to a sharp 90 degrees so it will strike a fero rod with ease to produce a shower of sparks. As this knife is made with O1 Tool Steel, it will corrode if you leave it out in the elements. Having said that, if you look after it, O1 is a great steel for Bushcraft knives.
What Is O1 Tool Steel?
O1 tool steel is a premium, oil-hardening alloy known for its ability to keep its shape even when subjected to high temperatures. The “O1” actually isn’t a reference to the steel’s popularity, but rather to its carbon content: around 1%. The O, meanwhile (not a zero!), refers to its oil hardening quality. Being a high carbon steel makes O1 hard and strong, but also more brittle and prone to cracking without proper heat treatment.
Important Properties
O1 steel offers versatility based on several strengths:
- Wear and abrasion resistance – Well-suited for cutting tools that need to maintain a sharp edge
- Toughness – Withstands impacts and stresses without cracking or breaking
- Machinability – Easy to machine and grind
- Corrosion resistance – Somewhat protective, although not as corrosion-resistant as fully stainless steels (such as 416 stainless steel, for example)
Composition
O1 tool steel is an alloy steel designed for high performance in various applications. It usually includes the following elements:
| Element | Purpose | Content |
| Carbon | Hardness and strength | 0.85-1% |
| Manganese | Hardness and wear resistance | 1-1.4% |
| Chromium | Wear and corrosion resistance | 0.4-0.6% |
| Tungsten | Wear resistance and toughness | 0.4-0.6% |
| Silicon | Deoxidization | 0.3-0.5% |
| Vanadium | Wear resistance and toughness | 0.15-0.3% |
This knife is a great choice for a Bushcraft knife. The overall length of the knife is 8″. The blade has a scandi grind. The scales are Gidgee with Red G10 Liners with brass pins. The sheath is made from Hermann Oak Leather and has a firesteel loop.
The firesteel is made using Gidgee from the same larger bit of timber that I cut the handles scales from. I cut the timber from a fallen tree near Charleville in South West Queensland. The firesteel is 9.5mm in diameter and 4.5 inches long (overall). I’ve also installed a quality “Made in Taiwan” Helikon-Tex compass in the rear.
