Happy Green | Master USA – Folding knife with tanto blade

The Happy Green by Master USA is a folding knife featuring a tanto blade profile made from 3Cr13 stainless steel. This lightweight EDC knife weighs 132 grams and offers a combo-edge cutting surface with a blade length of 95.25mm.

Construction and materials

Built with 3Cr13 stainless steel, the knife measures 215.9mm when open and 120.7mm when closed. The distinctive green color enhances visibility in outdoor environments. The liner lock mechanism secures the blade during use, while the tanto blade geometry provides additional tip strength for piercing tasks.

Application and use

This folding knife suits everyday carry and outdoor activities. The combo-edge configuration handles both precision cutting on the plain section and sawing through fibrous materials like rope and plastic on the serrated portion. Single-handed opening via thumb stud allows quick deployment when needed.

Integration and compatibility

As a balisong type product, this knife features standard pocket clip mounting for convenient carry. The liner lock mechanism provides reliable blade retention compatible with one-handed operation. No special tools or adapters are required for basic use.

Maintenance and lifecycle

The 3Cr13 steel requires regular maintenance for optimal performance. Clean the blade after use and apply oil monthly to the pivot point. The relatively soft steel composition allows easy sharpening with ceramic rods or whetstones when edge restoration is needed.
