is there a difference between oils
What is the difference between 3 in 1 oil and knife sharpening oil?

The labels.
3 in 1 may have some additional additives. |

Re: is there a difference between oils
Knife sharpening oil is usually food grade so therefore safe to use when sharpening for food use. 3 n 1 is a light machine oil. I think if I remember right 3 n 1 was made for guns, fishing reels, and sewing machines.

Re: is there a difference between oils
The purpose of honing (or knife sharpening) oil (or water soluble oil mixed with water) is to reduce friction (and thus heat) and keep the chips (particles) removed from the work piece in suspension (and usually flushed away in machine tool honing). Thus the abraded particles do not embed in and foul the abrasive media preventing it from performing its cutting action.
Cast iron engine block bores and mains are usually honed with a material that is essentially similar to kerosene and lighter than #2 fuel oil. The 3 in 1 brand of oil was originally advertised as "lubricates, cleans, and protects". It is basically a non-detergent motor oil and a little naptha. Think not; look up the MSDS for it and several non-detergent motor oils. |

Re: is there a difference between oils
Deshivs has the right of it; the labels are different. And (ahem) the price...
