I’ve been using the Tried and True Original (like you show) for the past couple of years on all utilitarian woodturner pieces like bowls and spoons, etc. Have also used on charcuterie boards and have been very satisfied with the results. A little goes a long way. I usually apply two thin coats and it’s good to go. No other waxes, buffing or anything else.
My understanding is that linseed oil is one of only a couple of the “drying oils”. *sorry, don’t remember where I read that.
I’m also an occasional user of Mahoneys Walnut oil for food grade products. That’s the oil I learned to use from a couple of my mentors. I like Walnut oil too but have found that sometimes it takes weeks or months to dry. Mahoney says to put it in the Sun for a day or so to help with drying. No biggie.
I’m a big believer that utility products like bowls need a finish that “just about anyone” can reapply easily as the wooden ware gets used, washed, dried, etc.
If you can find a Mike Mahoney demo he does a good job of explaining how he likes to keep it simple and effective.
I agree with
