One highly recommended EDC knife with a blade length of 3 inches or less is the Spyderco Paramilitary 2. It's a favorite among knife enthusiasts for its high-quality materials, solid construction, and ergonomic design. The Paramilitary 2 features a 3.44-inch blade made of premium CPM S30V stainless steel, which offers excellent edge retention and corrosion resistance.
The knife incorporates Spyderco's signature Round Hole for easy one-handed opening and a secure Compression Lock to keep the blade safely in place during use. Additionally, it has a textured G-10 handle that provides a comfortable and reliable grip.
However, the best EDC knife for you depends on your specific needs, preferences, and local knife laws. Before making a decision, I recommend conducting further research, reading reviews, and considering factors like blade material, handle design, carry options, and legal restrictions in your area to ensure the knife aligns with your intended use and personal requirements.
