If you want a personal knife for safety that will also be your all-purpose knife, a folding-blade knife is obviously the ideal choice. For a durable knife that will last a lifetime with regular care, expect to spend around $150, but there are plenty of knives for less than $100 that are perfectly suited for sailboat racing. If you choose a strictly serrated blade, it’s probably best to keep it for safety, not regular use. In this range, you’ll find many knives popular among sailors, including knives from such manufacturers as Benchmade, Wichard, Spyderco, Boye, Gill, and Gerber. Most chandleries and online marine stores stock a variety, but the only true way to meet your personal fit for one-handed opening is to try one before you buy it. Once you buy one, learn how to use it.
