Knifemakers Bear OPS added eight new models to their expanding line of butterfly knives. These tough, durable knives have Bowie clip blades made of premium 14C28N stainless steel, which provides a combination of edge sharpness, edge retention and corrosion resistance. They are heat treated to an ideal Rockwell hardness of 58-60.

As any knife aficionado knows, one of the advantages of a butterfly knife is to have a long blade that folds into a long handle. There are currently four new Bear Song IV Pattern 400 models being release. Each has a 3-3/8” edged satin-finish blade that folds into a 5-3/8” handle. The Handles on these knives have a T-6 aircraft aluminum construction, in addition to water-transfer coating of Blue Drop, Pink Drop, Carbon Fiber and the Reaper Z coating from the Undead Series.

In addition to the four new Bear Song IV Pattern 400 models, there are also four more compact Pattern 450 models which have the same features and coating choices with a 2-7/8” blade in a 4-1/4” handle.

All Bear OPS butterfly blades ride on bronze phosphorous washers for smooth opening and closing. Prices range from $137.50 to $145. All products by Bear OPS are made in the United States and are backed by a Lifetime Limited Warranty. Bear OPS is a division of Bear & Son Cutlery, a world-famous knifemaker and manufacturer.
