I used to work in the food industry and still have a roll full of various knives... the choice is very subjective but there are some knive styles that are less/more desirable to use.
A Chef's knife as pictured above is a general purpose knife and can do the job but is more suited for board work like rock chopping.
A Santoku would be one my my last choices (too small) and again more of a veggie/board knife.
The Scimeter is a thick strong meat cutter's knife and can do the job but more suitable for big jobs like separating larger cuts.
A Boning knife works but is more suitable to separate meat from bone like deboning a chicken breast.
Another option is a
Breaking Knife, these are also meat cutter's knives but more nimble than a Scimeter but also a thick strong knife. No problem steaking a salmon or cutting through rib cartlidge with either a Scimeter or Breaking knife.. I would not attempt that with my Chef's or Santoku knife as I like to reserve them for board work as opposed to working around bones which will dull or chip them fast.
After a knife style, you will need to decide on a manufacturer.. there are many to choose from and many are over priced, but here is where you will get many opinions. Forschner/Victorinox are popular but not the only ones in their class.
Dexter Russell also makes some quality knives.
All knives dull over time and useage, it's more important to have a suitable sharpening system than invest in a expensive knife.
