Prohunter sharpening steel with plastic handle. We recommend using the sharpening steel to maintain the knives. If you are going to effectively maintain your knives before use, then ironing steel is a good option. Stroke the knife very slowly at an angle of 15-20 degrees. It is important that you do it slowly and that you iron the "egg" in one and the same coat. You should do this 4-5 times, on each side of the knife blade.
