For me, as a beginner, what type of blade recommend you?
In general, carbon versus stainless steels has several factors to consider which may not be relevant to your use.
Carbon steels will strike a ferro rod to start a fire, stainless won't.
Carbon steels are generally easier to sharpen with simple tools.
Carbon steels will generally tolerate prying better.
Carbon steels will generally take batoning wood better.
Carbon steel edge holding is generally better and can take a steeper (thinner) edge bevel.
Stainless is a lot easier for most people to take care of.
Stainless is generally better for novice users.
Stainless is rust resistant and a good choice long term storage.
Edge holding is generally more than adequate for most users.
A seemingly dull knife (on most stamped stainless steels) can be restored by running the edge against a hard edge to straighten the cutting edge (think common 'sharpening' steels in knife blocks which re-align the edge).
Stainless will generally bend and not snap when pried beyond its limits.
This assumes common non-super steels so, common stamped stainless varieties and simple carbon. Moving to Powdered Metals and complex metallurgy is a whole different topic and overwhelming for most novices. This also assume simple heat treats, skipping differential heat treats, cryogenics, etc.
