Drop point/shallow clip point is usually better for a utility knife but if you have your own reasons to prefer a tanto configuration it's all good. Don't worry about the steel too much - it's really just a fad these days. 440C, 12C27 or any other "wonder steel" out there will do the job as long as the heat treatment is right. Don't fall for the hype and don't shell out too much extra $ for a fad steel when you could get basically the same performance blade in a much cheaper knife. IMHO any folder over 100$ is a waste of money but then again, the final decision is up to you.

Spyderco makes pretty good folders at competitive prices. Most designs are a bit space age and some are too specialized. But a workhorse like the Endura would serve you well.

Also, you're looking for a folder with a 4-5" blade. That's pretty big for a pocket knife. Some of the larger folders on the market are pretty beefy and might be too bulky for comfortable EDC.
