Krefcenz - I have all three knives (well I have just sold the mini grip) and there is no comparison between the 3.
The sebenza is in all ways a superior product, as you would expect, but no allways get, in a knife that cost a multiple of the price.
If the mini grpi had had a round spyderco hole instead of the oval it would have been my favourite FRN handled knife I had ever owned but it is a cheap(ish) FRN handled knife and does not pretend to be anything else.
The 705 is no where near as ergonomic as a sebie, at least not in my hands and way too much kinfe sticks up above the clip to carry comfortably IWB and this also makes it show up big time if carried in your front pocket.
Other than for specific tasks (eg light weight for jogging with) I have not bought any other folders since I got my first sebenza six months or so ago.
I now have 2 and a third on order. I have been buying "quality knives" for over 10 years now to find my ideal EDC and have no stopped with CRK.
The best thing is to find a shop where you can handle all the knives you have in mind and take it from there.
I am not saying the the Sebenza is perfect but IMHO it is the best I have come across by quite a wide margin.
