They are different materials used for the kote and for trim pieces. In a beginner's set, the trim material is not so important but you should pay attention to the palms of the kote. The most common palm material in CHEAP kote is cowhide.
Cowhide palms tend to get progressively stiffer with use (they loosen up after you sweat into them a bit, or wet them down), which eventually causes them to tear. Theonly advantage to cowhide is cost. Expext to repalm or replace kote with cowhide palms after about 2 years of recreational use.
Tanned deerskin is superior to cowhide in that it tends to remain pliable after repeated soakings in sweat. A good set of deerskin kote can last 5 years or more of recreational use. Clarino is artificial leather.
Like cowhide, it gets stiff with sweat but it can be washed and becomes pliable again. Some people report they like their clarino palms very much, while others think they are a waste of time and money. The concept of clarino is to offer something ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
