I like to take a MINIMUM of 3 knives with me into the bush - something big & full tang that can handle the 'hard use' tasks, I have several candidates for this:
BK-9
HI Khukuri
ESEE Lite Machete
KA-BAR Kukri Machete
BK-7
Secondly:
I also like to have a smaller knife with scandi grind for carving and finer work, that would be one of my Mora knives.
Thirdly:
I like to take a SAK for the multiple useful camping tools - saw, scissors, small knife, file, can opener, bottle opener, tweezers, etc.
Then once I have my 3 core knives sorted then I'll add 2 or more other knives to take for playing with/backup/certain tasks. My steak (food prep) knife might be one of my stainless Mora knives or an Opinel knife.
Of course there is nothing to say that my steak knife at home wont be something other than a cheap serrated steak knife from the kitchen drawer. I actually prefer to use a 'sharp' plain edge blade to cut my steak anyway. I am happy to use one of my Opinel knives to eat steak at home, my fancy one is the #8 stainless with walnut handle - it slices steak just fine! Last Xmas at dinner with the family I checked mum's drawer and found that all the steak knives were in use and the drawer was empty, I fished in my pocket to see what I could find and pulled out my Opinel #6 carbon - that sliced my steak quite nicely thank you! I'm sure I could have gotten by with using my Izula as a steak knife, of course.
The obvious question for the OP is what knives in particular are we talking about when he mentions knives for bushcraft that look like cheap kitchen steak knifes?
What bushcraft tasks are these knives intended to be used for? Food prep? Carving? Skinning?
If someone goes into the bush with an axe and a knife then what tasks will that knife be needed for?
If you are buying a knife then you need to consider what the various tasks are that you will use the knife for and buy something that can handle those tasks & more. If you carry a SAK that can handle fine cutting then maybe a larger stronger knife will handle everything else or maybe you don't want so much weight if you are hiking long distances? An ESEE-3 or ESEE-4 might be the idea general purpose knife without too much weight or you might want something stronger like an ESEE-5. They are all good and which is best depends on your needs & wants.
