What is the best survival tool that is both handy and inexpensive? It is a tactical knife like (TOPS Knives). A tactical knife with a semi-serrated edge, a good locking mechanism and single-handed opening feature is the perfect safety equipment that can help you no matter in what situation you are. Here are four tips for buying a tactical knife:

• The rule of thumb for buying a good quality tactical knife is to avoid the cheap brands. Go for a moderately priced knife from a reputed brand. Look for features like edge holding capacity, blade design, strength and durability.

• The steel of the blade is the most important aspect of the knife. Tactical knives mostly employ 440C, ATS 34, D2 and AUS 8. The type of steel used in the blade will determine the strength of the knife, its ability to withstand stress, toughness, rust and stain resistance etc.

• A folding tactical knife should have a good locking mechanism. You can go for a liner lock, a spine lock or choose from the endless options available. Avoid buying an automatic knife as they are not as reliable as one with a proper locking mechanism in place.

• Look for a semi-serrated edge. This makes the length of the cutting edge longer than the length of the blade. A chisel edge is also recommended as this makes the edge sharper.
