A few times I've bought friends a good fillet knife for around that much after seeing what they had in their tackle box. Can normally find a CRKT or Gerber with nice grippy rubber handle on sale. I just find those walmart style, plastic hollow handle fishing knives so offensive.
Stayed at a friends house awhile ago an they had these.

They were very nice to use.
