i think i would ask myself what i really wanted to do with my knife!?
i only use my knife for small cutting work, pot holders, small shaping work on thin twigs and branchs for pegs etc and food prep.
so for a cheap carbon edged knife an Opinal No8 would and does suffice, i have a heavier bespoke knife i have carried around for years and hardly used, if i need any heavy stuff doing its either a small hatchett or a folding saw.
everyone has their preferences, if you only want to carry one sharp item then go for an allrounder especially if you like to 'put them to the test' ;-)
i have a nice nessmuk style blade i got off a forum maker and handled it myself, thats very nice to handle and work with, a good shape for food prep.
as i said before, ask yourself what you want to do with it and then chose the tool to fit the job.
only my opinion and not meant to offend.
Adam.
