MichaelJ get a RSK MK3 I have one and like it. All the knives that you put in your thread I have. The Grohmann 1 and 3 are easy to get and do not cost as much as the MK3 and the howling rat unless the company is getting there knives out faster than they use to take so lnog to get I think mine took all most 9 weeks. I called and to order a MK3 and had it in 3 days. They are a great knife. I have ordered from Grohmann and they are pretty quick at getting a knife to you too.
Good luck in getting your knife picked out. The MK3 is one sweet knife though.
Take care,
Bryan
