Or, you could buy a blade and handle it to suit yourself

Best one ?
what are you likely to actually use it for ? and what size are your hands, etc., I have a laplander blade that Warthog1981 handled for me, and it's excellent. I also have a Spyderco bushcrafter that Chris Claycomb handled for me too though, and it too is excellent
and a Falkniven WM1 that Leon_1 made for me from a blank blade, again it's a brilliantly useful knife.
Best advice is maybe to get a chance to try several and see which works best for you.
