It can be a hunting knife, a fighting knife, a rope cutter, or whatever your cutting needs require. It also has a securely lockable blade that can be put into a pocket when folded, making it convenient and safe for the owner to carry around. In this category, portable folding knives are widely popular among established knife companies as well as emerging companies because of their completely professional features. Its typical design includes: There is usually a hole or latch to control the blade with the thumb, so that it can be opened with one hand, and the attached knife clip allows the folding knife to be tied into a pocket for easy carrying and removal. There are also spring-backed or padded blade locking mechanisms. The price of a knife depends on its manufacturing process and materials. For example, a knife with a titanium alloy steel handle is more than $100 more expensive than a knife with an ABS synthetic plastic handle. A knife with a special high-quality steel blade (such as ATS-34 steel, or even ceramic, Damascus steel or titanium steel, etc.) will be more expensive than a knife with an ABS synthetic plastic handle. Ordinary economical steel (such as 420 steel, etc.) knives are much more expensive. The reputation of the manufacturer and the place of production also make the retail price of knives vary greatly. Just like you have to spend a lot of money to get a Rolex and a Titoni watch, you also have to spend a lot more to get an Emerson or Gobo folding knife. If you need to purchase a co-manufactured custom knife or a knife with a patented design, you will need to pay an additional fee. The following tips can help you buy a satisfactory folding knife from a knife store. The most important factor in choosing a good knife for yourself is how you feel about it. Put it in your hand and feel it to see if it's ideal. Open it with one hand and test whether the opening hole or latch or other opening mechanism feels best. Then take a look at its locking mechanism, whether it uses back spring locking or pad locking, and whether it is safe and comfortable. Is the blade the size you want? If you plan to use the knife to cut fiber rope or cardboard, you should choose a half-tooth blade. If you want to use it to cut only fiber ropes, then you should choose a full-tooth blade. You also need to consider the material of the blade and handle. For example, whether the blade is long enough, what is the steel material, and whether the handle is strong and not easily damaged. You also need to weigh whether the price you would pay is worth it to you. One last look, where it comes from. Is it made in the United States, Germany or Japan, or in a country or region where labor prices are very low, such as China or Taiwan. The knives produced by the latter do not pay attention to craftsmanship and are of low quality. But some are provided by American companies with high-quality materials and are only assembled overseas. The knives they produce also have high standards of quality control and are of good quality, but the prices are more affordable.
