The combo tool is a great piece of engineering, IMO. For your needs, does it do enough to replace the Cap lifter/Large SD and the Can opener/Small SD on other models?
Let's compare features:
Combo tool:
- Cap lifter
- Can opener (work backwards)
- Flat SD (tip can be used on Phillips)
- Wire stripper
- Pry bar
Cap Lifter/large SD
- Cap lifter
- Large flat SD
- Pry bar
- Wire stripper
Can opener/small SD
- Can opener
- Small flat SD (can be used on Phillips)
I phrased the question per your needs. Objectively, a dedicated tool is always better than a compromised one. The two drawbacks I see with the combo tool, is its size and the Phillips capability. There will be lots of slop when engaging a large flat head screw. Also, it has less prying power. To drive Phillips, you have to hold it consistently at an angle, which is harder than using the in-line small SD tool. The advantage of the combo tool is that it saves room for other tools, or makes the knife one layer thinner.
For my needs, the combo tool is good enough. I don't have a constant need to pry or turn Phillips screws.
