Hi Patrick,
I am lucky enough to have on each of the Cheetlang and Reiger.
The Cheetlang is about 18"long and very fast and agile in the hand. It feels guite a bit lighter than the Reiger, but not too light. It chops well on lighter small stuff,3" and under I find it quite perfect. You need to develope a certian hold on the handle so the back of it does not bite your hand while chopping. Once you find this hold it is a joy to swing. This one feels more like a weapon than a tool. It is a beautiful knife to own. One of my favorites!!
The Reiger on the other hand is very weight forward and is a real super chopper.
It is around 19" plus a little. I am at work and do not have them here to actually measure. The deep bend of the blade on the Reiger and the thick powerful blade make it a true powerhouse to use in the field. The American style of handle is real nice to hold on to . I find that it is a bit on the thick side as far as handles go and tends to test your grip strength more than the slim handle of the Cheetlang, but this is not really strange, as the handle on my 18" AK is a very full grip also. I suppose the Kamis make the handle girth acording to the heft of the blade. Or mabe it is just feel that each one goes by. If you are trying to decide between the two as to which one you would want to buy. Reiger is chopping tool to me. The Cheetlang is a speedy tool of defence. IMO that is.. Take Care and Later All................
