Fairly well known issue but little known solution. The KiTech tips suffer from the chemical process used to cure the tips by omitting the manual steps present in older manufacturing techniques. The older processes relied heavily on press-fit techniques using hyrdraulic machinery that would increase the internal temperature of the leather during the press-step, resulting in a stratification and porization of the leather, giving the chalk more room to impregnate the leather, but also hardening the protein-fibers at the same time, resulting in a well-shaped tip that also held chalk very well. Two options to fix this. One, adding the press-fit temp step by chemical proxy, by bathing the tip in 350 degree ewe's milk (ewe's milk is a must); or two, just applying chalk to the untreated tip before you shoot. If following the second step, you may wish to occasionally debride the glossy layer that sometimes develops with an abrasive. Sandpaper works fine, but special tools also exist for this purpose.
