We recently received an inquiry from a customer wanting help with obtaining the ideal sharpener and a suggestion for a great field sharpener. His inquiry and our response is this week's blog post.

The black colour is provided by a thin layer of Teflon which has a protective part. Regrettably this layer deteriorates pretty rapidly if the knife is utilised intensively.

Just after making use of your knife normally wipe the blade with cleaning products meant for knives, to get rid of any residue or grim on the blade. It is better to use a single of the several multifunction cleaners that you can use on wood, metal, and leather, and with these cleaners, you will not need to worry about your deal with obtaining tarnished or cracked.
