I hope you are still enjoying your time in South Korea. A former work colleague spent a year teaching English in Korea also. He described it as an interesting mixed experience but overall he liked it and said that he would consider spending another year. Have you made a permanent move to Korea for the career change?
On to your picks. WOW! I am in awe of your skills and talent. It was inspiring and uplifting to look at the body of your work. You and legion303 have established a benchmark for homebrew lock picks. The only problem is that -- at least at this stage -- I feel that anything I produce will fall short of the standard you have established. I am being naive in aspiring to produce the quality of work that you produce?
One of your designs I had seen it before. It took me a moment to recollect where I had seen it and it was in the Goso catalog:
Did they copy you or did you copy them? If they copied you that would be awesome!
I do sincerely hope that you return to custome pick making. You are offering something very special to the lockpicking community. There is definitely a market for your work and it is plain that the owners of your picks cherish them.
