My folding knives has gone dull—what’s the quickest 4-step way to get it razor-sharp again?

1. Clean the blade with a soft cloth to remove oil, dirt, or debris. 2. Soak your double-sided whetstone and set it on a non-slip surface, coarse side up. 3. Hold the folding knife at a steady 15° angle and push the edge evenly from heel to tip 10–20 times; flip and repeat on the other side. 4. Turn the stone to the fine side for a quick polish, using the same gentle motion to restore a hair-popping edge.
