I have never run across one like that. I am not saying it does not exist, I just have not seen one.

That is an interesting idea but I am wondering how practical it would be. I am thinking that the engineering limitation would be the razor blade but less so the utility blade. The razor I think would not be rigid enough to handle cutting anything of much size. I have only seen disposable razors like the ones used in the scraper and they have a rigid back attached. I am guessing there is about 1/2 inch of blade exposed? That would be your cutting limit. I also don't think they would last very long cutting woodier things.

The utility blades on the other hand are definitely more rigid. I just have not seen a pruner that takes them as their blade.

I assume you don't like sharpening and would prefer cheap blade replacements?

I only have by-pass and have not like anvils from past use. They seem to get out alignment and dont cut the last little strand. Could have been that they were cheap though.

Just curious where you find that you would prefer anvils.

Sears used to sell an anvil cutter with replaceable blades. If I remember correctly it came in two sizes. One was large enough to cut rubber hose. I don't remember what Sears called them.

I had forgotten about that. My mom actually bought me one of those. It is called a Handi-Cut. There is a fairly complete review here.

Mine (about 6 years old?) is heavier than my pruners. It cuts well but I did not think to use it as a pruner. I still would not use it as one even after the suggestion. The blade is just not heavy enough for woody plants and the thing is heavier than I would like for lighter plant cutting.

In the time I have had mine I have used it maybe 5 times. Definitely not a go to tool in my box. I find the utility knife to be more versatile. The Handi-Cut is definitely better in some situations but not as flexible as the utility knife.
