Sailing Knife Buyer’s Guide

Best Sailing KnifeSailing knives are an important tool for boaters.  A good, quality knife is essential for safety because a cheap or dull knife is more prone to slipping or breaking, which can lead to life-threatening cuts to a boater’s hand or arms.  Our buying guide reviews knives of the highest quality which you can choose for worry-free seamanship.  These knives include several features that are very handy for boaters.  When choosing a boating knife you will want one that is so useful and comfortable that you will always have it with you.

Boating Knife Features Include:

Boating knives include several features unique to boating.  This guide will help you to understand the purpose of these features so you can choose the right knife for your boating needs.


Marlinspike seamanship is becoming a lost art, but there are still times when it is an essential skill.  Older ropes used on boats were typically made of triple-braided nylon, cotton, or sisal.  These braids could be un-woven and re-woven by mariners to form a splice to create an eye at the end of a rope or to splice together shorter lengths of rope.  A marlinspike is used to separate the strands of rope so they can be spliced together to create a new shape, such as a loop.  This is becoming a lost art because ropes are available today pre-shaped into whatever loops a boater could need.  However, even if a boater does not intend to do much splicing, a marlinspike is still a valuable tool because it can be quickly used to pry open tight knots.

Shackle Tool

The shackle tool is unique to sail boaters.  Shackles are clevises used to attach sails to rigging.  The shackles lock tight, and a shackle tool is used to quickly unlock the clevis.  Sailors who do this frequently should choose a boating knife that is comfortable and convenient because they will want to keep this knife handy at all times.

Stainless Steel

Any knife designed for boating use should be stainless steel because it resists rust.   A quality stainless steel knife will last a lifetime, but it should still be periodically oiled to protect and maintain the knife.

Serrated Blade

Serrated blades are typical of boating knives and help to distinguish a boating knife from a regular pocketknife.  Serrated blades have a saw-tooth look, and are useful for cutting ropes safely.  It is important to remember that a sharp knife is a safe knife.   Using a non-serrated blade on a thick rope on a rocking boat is asking for trouble because one slip of the slick blade could slice a boater’s hand.  Serrated blades can be sharpened but the method is a bit more involved than a straight blade.  The round serrations on a serrated blade are sharpened with a small, round, oiled sharpening stone in the shape of a file.

The knives reviewed in this guide will serve boaters well.  All of these knives are made with quality, stainless steel construction and they have unique features that will serve each boater’s needs.
