Light and light travel - from what is a good "nail"

The so-called "nail" refers to the ultra-light nail. When it comes to ultra-light nails, you may easily think of the "toothpick" titanium nail. In order to achieve ultra-light weight, the toothpick is too thin in diameter and the friction surface of the soil is too small to be gripped with an impractical label.

Full Metal Jacket has a nail divided into 4 parts, a nail cap, a tube body, a carbon core, and a nail head. In addition to the carbon core, the other parts are 7075 aviation aluminum materials, common pole materials. The nail is 6 inches (15 cm) long and is the same length as a normal aluminum nail. It does not feel too short to reduce weight.

The point is that it weighs only 5.5 grams, and the four nails are so light and innocent in your hand that it is a surprise. The outer aluminum skin was painted with black stripes. At first I thought it was carbon without aluminum skin, but when I was in the air, several nails collided with each other and creaked, let me know that it was indeed the outerwear of Iron Man.

The feeling of holding it in my hand is also extremely embarrassing, not long or short, the electronic scale shows only 5 grams.

FULL Metal Jacket nails (referred to as FMJ nails) are available in many comprehensive ultra-light equipment manufacturers' websites. The price is very high, and the price is calculated to be 8 to 10 knives. If you charge the freight, each one is small in RMB. About 50 yuan. The average two-person tent, the demand for nails is about 11 to 15, if all are equipped with 15 FMJ Iron Man nails, it will be nearly 800 yuan. Therefore, in use, it is still necessary to match with titanium nails. Because the tent angle is not subject to great force, titanium nails can be used, and the wind rope and the hall must be firm. 4 to 6 FMJ nails can be used in combination.

Of course, using this nail, it will not match Chunhui, Qiu Meng, and Lengshan tent, and it must be matched with the ultra-light Cuben account. Otherwise, the tent, such as the Terra Nova Laser Ultra, is about 500 grams, and a common nail is close to 200 grams. What is the significance of the weight saved by the ultra-light tent?
