You are right, electrolytic rust removal is far-and-away better. You'll often be able to recover even etchings, makers marks, etc. that the acid bath will have destroyed. A concern, particularly for tools that flex (like hand saws) is hydrogen embrittlement. This, however, can be counteracted by baking the tool at 350-400 degrees for four hours or so immediately after being removed from the electrolytic tank. I'd recommend sodium carbonate (washing soda) instead of bicarbonate.
Fantastic job! Thank you!
