Three-in-one oil should not be used for sharpening. Mineral oil and additives make up 3-in-1 oil, a versatile lubricant. Although it might function as a general-purpose lubricant in some circumstances, it is not intended for honing or sharpening blades. It's better to use honing oils or lubricants made especially for the job during honing. Honing oils are frequently made of mineral oil and have particular qualities that aid in the sharpening process, such as viscosity and suitable lubrication. When sharpening your knives, these oils work better at preserving the ideal angle, lowering friction, and producing the best results.
