Materials

RoCK knives are made from your choice of High Carbon 1095 or O1 tool steel. These steels have proven to be long lasting, edge retaining, and easy to maintain.

So, what’s the difference??

Metallurgical differences are easy to explain. According to BladeHQ these are the chemical compositions of 1095 and O1.


Comparison of 1095HC and O1 Tool Steels per BladeHQ

So what does this mean? 1095 is what is known as a ‘Simple Steel’ . You take iron, add just a few ingredients (in this case, Carbon and Manganese).

Carbon is what gives steel its ‘hardness’….well not exactly, technically its the carbon carbides that are formed as the metal is quenched during the hardening process, but let’s just keep it simple for this discussion. These are also what gives 1095 that superior ‘sharpness’ that many professional chefs prefer. A properly cared for Carbon Steel knife will (usually) obtain a higher sharpness than a ‘stainless’ steel knife. I say usually because there are many factors that we will not get into here.

By contrast, you can see that O1 has a few more ingredients, and these change the recipe giving it a few other more useful properties for its intended purposes. Yes it has an almost identical Carbon content to 1095, but is has much higher Manganese content (reduced brittleness) and adds Chromium and Vanadium to give O1 its signature toughness and wear resistance! Again, it is often used for making tools, so it needs to be tough.

Why choose one over the other?

Because this is America and we are all about choices!! But actually it comes down to your ‘philosophy of use’ (Thanks Chris Tanner!). If you are a bushcrafter and you want something easy to sharpen to a keen edge and can whittle wood all day or process the days catch into dinner 1095 is your steel! If you need something a bit tougher to process wood, maybe help dig a hole (don’t cringe guys, it happens!), then maybe O1 is your metal of choice.

Both types require a little maintenance. Wipe them off after use, rinse with hot water, dry them and apply a little bit of oil to the blade (cooking, animal fat, or even oil from the side of your nose if you have to) will keep your blade rust free and ready for action!

Handle Materials:
We have several choices of hardwoods, or hand-laid micarta.

Micarta is a VERY strong material made of layers of paper or fabric permeated and bound together with strong epoxy resins! All this means it is structurally strong, can take a lot of abuse, provides a great grip, and will probably outlast the blade (which itself should last longer than a lifetime if taken care of correctly!).

Why Canvas or paper? It really depends on color/texture desired. Brighter colors like lemon, Zombie Green, bright reds are usually paper colors.

Cloth or Canvas micarta can be made from any absorbent material.
Stock colors are Black, Olive Drab and Desert Tan.

Woods are beautiful, resilient, and feel warm in your hand. Icarry a stock of nice beautiful woods: Walnut, Cherry, Maple, Desert IronWood, African Blackwood, Cocobolo, and Ebony.
**Additional charge of $17 for Verawood or Lignum Vitae handle scales.
