Rada Quick Edge Knife Sharpener vs SHARPAL 191H Knife & Scissors Sharpener

Buy the SHARPAL 191H if you want one compact tool that handles serrated blades and scissors as well as plain knives, with a suction base for one-handed use. Buy the Rada Quick Edge if you mostly sharpen straight-edge kitchen, fillet or hunting knives and want a simple two-pull tool backed by a lifetime guarantee. The Rada's dual hardened steel wheels sharpen both sides at once and owners rate it very highly; the SHARPAL adds a carbide repair stage and ceramic honing stage but has a shorter three-year warranty and a lower average rating.

• Choose the Quick Edge if you sharpen plain-edge knives often and want a fast, foolproof pull-through with a lifetime guarantee.
• Choose the SHARPAL 191H if you also need to sharpen serrated knives and scissors and want the tool to stay put on the counter.
