Overall This is a substantial, weighty and extremely well-made tool for writing, which was quite obviously produced by skilled craftspeople, using top-quality materials. The bullet-like shape and long lines of this pen really do evoke images of fighter jets and other weaponry. This is a sleek, precision tool, for sure, and not a toy. Extremely easy to use. The pen is superbly balanced and accepts common Parker-style refills. The twist mechanism locks and operates like a well-oiled, precision tool. Completely true to its value. This is a sumptuous luxury item, made of fine materials, and it rewards its user with a certain tangible prestige.
