The Kapoosh knife holder is a unique new system to hold any knife any time, no need to find a specific slot to slide knife into. The Kapoosh utilizes fredom rods, which allow you to mix and match kitchen knives form different sets and to store practically any utensil easily - anywhere in the block. Plus the rods keep your knives sharper by eliminating the potential of scraping blades on the edges of traditional knife block sets. These rods are removable and dishwasher safe. Just place the freedom rods on the top rack of your dishwasher for cleaning. This Kapoosh has a stainless steel exterior.
