It is a steel truly worth of handcrafted knives.

It is a low alloy design with:
- the best hardness-toughness ratio
- excellent forgeability
- good wear resistance
The new steel for high performance knives.

ApexUltra is finally available in 2.5 and 3.6 mm!

We have been waiting a long time for this and the sheets have just arrived in our workshop.

It is the first time that ApexUltra becomes available in typical stock removal dimensions. The sheets are large enough for waterjet / lasercutting so we are excited to see more stock removal and production knife makers jump on this for their high performance knives. Of course these sizes are also very handy for making damascus with ApexUltra as you can achieve higher layer counts in the first stack compared to our 5mm stock sizes.

Sheet sizes are:
3.6*800*1050 mm and 2.5*1080*750 mm
[0.14*32*42" and 0.1*30*43.2"]

What's your first project going to be?

ApexUltra will soon also be available as 2.5 and 3.6mm sheet metal! We've been waiting for this a long time so we are excited it should only take couple of more weeks now!

Finally we will have the right cross sections for stock removal blades, laser and waterjet cutting blanks for batch productions and whatever else you will make from it.

Let us know in the comments what sizes you want us to cut the gigantic 4*2m wide resulting blanks to! We are trying to find the best standard sizes to fit everyones needs.

Next week the blocks will be rolled down to final thickness. Then heat treatment and surface blasting will take another 2-3 weeks before the sheets are shipped to us and then cut to size. So all in all we expect them to be ready for shipment from Austria in about a month.

Today is a very special day for us as the first industrial batch of ApexUltra is being molten, alloyed and cast!

We thought that was the perfect opportunity to send out an email with all the specs, the chemistry and the details on the pre-sale.

Is ApexUltra easy to sharpen?

Despite the high hardness, it is rather easy to sharpen and does not require special diamond sharpening tools. Whetstones and leather strops are effective for knife care, and with the high hardness and fine structure very fine edges can be achieved. A very fine honing rod can also be effective as long as care is taken not to damage the edge.

How do I heat treat ApexUltra?
There will be a variety of recommended heat treatment protocols for you to chose from once the batch has been delivered to us and we have had the chance to test this exact batch. We will make sure that there is a recommended procedure for different hardness levels and applications and with Larrin’s new video about heat treating in the gas forge out, we are even playing with the thought of adding a recommended procedure for gas forge heat treatment. ApexUltra is designed to have balanced hardenability: high enough that full thickness knives will harden in oil without using a risky water quench. But low enough in hardenability that the steel is easy anneal by placing in slow cool media like vermiculite or perlite.

Which knives is ApexUltra best suited for?
With its combination of high hardness and toughness ApexUltra works very well in knives with thin, acute edges. Culinary knives, razors, and carving knives are examples of good applications.
