You could use something in a similar tone but with a different finish.

beckysharp Reinstate SW Unconditionally thank you it looks like their unpolished satin brass might be a good match.

As a side question if the knob is large enough, could it be used on a refrigerator or must you have a pull since it's so heavy?

You need a pull. A knob won't work.

Alternately, is there a knob at Armac Martin that's close enough to the DeVOL, where there's an entire collection/suite of Armac Martin hardware from which to choose?

I would look at AM's Cotswold 3004 Bun Knob and their Withenshaw Knob, and then select AM appliance pulls, and then choose the same finish for all. That would likely be the easiest way to proceed.

I guess what I really like about them is how textured they are. In the process where they make their hardware, they add in some sand. I wonder if there is any other hardware manufacturer who does this

The process is sand casting. I would check Rocky Mountain Hardware and Horton Brasses to see what they have.

beckysharp Reinstate SW Unconditionally thank you so much! Between Rocky Mountain and Sun Valley, I think I will find something that can work!

Try "Look in the Attic". They carry a lot of pulls make by Copper Mountain Hardware and much of it is unlacquered solid brass.

@Malcolm what did you land up with for hardware. I love those knobs too.

@Malcolm I'm currently in the same situation. What did you end up purchasing?

Malcolm I’m curious to know as well. I’m in the same boat
