I don't really know that much about Mr. Kim personally, except that he was the chief designer during what I refer to as Surefire's "golden age", which includes the "empty bezel" versatility of the P/C/Z/G lines, as well as the E1E/E2E series; not to mention many other models. I'm referring mainly to the flashlights I own and am somewhat familiar with, though there are others here whom I'm sure are far more knowledgeable about his technical contributions. When Mr. Kim left, the body styling changed and the bezel versatility left, for the most part. He is the man. I would be thrilled to meet him in person, and I would shamelessly and slavishly garland him with verbal accolades.
