A sharp knife is only as good as the last time it was maintained. The Marttiini Sharpening Steel is a straightforward, reliable tool designed specifically for keeping kitchen knives and filleting knives in working condition between sharpenings.

The 10-inch steel alloy rod realigns a blade's edge with each pass — restoring sharpness that dulls through regular use without removing significant metal the way a whetstone would. This makes it ideal for quick touch-ups before or after use, particularly for fillet knives that need to stay keen through an entire cleaning session. The rod's length suits both kitchen knives and the longer fillet knives in the Marttiini lineup.

To use, hold the steel vertically with the tip resting on a stable surface, then draw the blade down and across the rod at roughly a 20-degree angle, alternating sides with each stroke. A few passes per side is typically all it takes to bring an edge back to life. The handle is molded plastic with a sure, comfortable grip and a hanging loop at the top for easy storage on a hook or knife rack. Clean the steel with warm water and dry thoroughly after use.
