I think maybe the new style toe kick saws which is a small circular saw with an extension base on it OR an oscillating saw and I guess even a reciprocating saw.

I've never had a wood cutting blade on my angle grinders nor will I ever try it. Judging from the occasional kickback while grinding metal I think cutting wood is a quick way to the emergency room.

Perhaps one of these?

I looked at those. When the base is flat against the workpiece, how much clearance does the back of the handle need? I attempted to measure that from the pictures I found, and concluded that it's little if any better than the toe kick saw. But if you have one and will measure it for me, that would give me better information.

Sorry, not a tool I've ever even seen in person or had any occasion to need. I'd probably use a hand saw like a Japanese saw in a tight space.

Did you look at an image of the toe kick saw I suggested?

You didn't post a link or a picture before, and the ones rweigel posted (and the others I saw when I looked at them) did not meet the need. Now that I see it, I can see that it would do what I want.

I'd rather have one tool that does two jobs, but I'd rather have a tool that does this job than not have it! Thank you.

But the picture doesn't show a product name or brand name. Can you tell me who makes it? I already know that if I just search Amazon for "toe kick saws" I won't stumble across it.

Sometimes called a "flush cut saw". If you do a google search you will find quite a few. I did not see any big brand names however I did not do a deep dive. You will see them in Amazon, in Canada anyways. Note I am in Canada.
