The stainless steel used by Marttiini is easy to maintain as a blade material. A stainless steel blade remains sharp for long. Chromium makes up 13% of the steel mixture and the hardness of the mixture is 53-54 Rockwell units (HRC). A diamond sharpener is recommended for sharpening chromium steel.
The traditional material used for Finnish knife handles is curly birch. The material comes from the curly birch belt in Central Finland. The blaze-patterned curly birch is an excellent fit as a material for a knife handle, because it's durable and fair. This beautifully patterned curly birch is available on the market in limited amounts, which makes the price notably higher than regular birch.
