Rounded versus Straight Concave Cutters?
« on: December 26, 2011, 05:19 PM »
Happy New Year to you all!

I'm looking to upgrade to some stainless steel concave cutters, and I'm wondering if there is anything other than personal preference that would make it worth the price difference (20 bucks or so more for the rounded ones at Dallas)...

I'd love to hear about your experiences!

unfortunately they are two totally different tools in my opinion. If i had to choose one as the stainless(better quality) i would choose the one that is most commonly used out of the two- the straight concave cutter. However if you dont currently have a curved concave cutter but you have a straight concave cutter than i would buy the curved so you have a new tool in your arsenal.

I'm not so sure the stainless are "better quality".  Yes, it's true they won't rust, but usually the carbon steel ones will be able to be sharpened sharper.  If cost is an object, I would buy the carbon steel ones, and take good care of them.

Thanks guys! I'm not quite understanding how the two tools are so totally different... If you look here http://www.dallasbonsai.com/store/stainless_steel_bonsai_tools.html, I'm debating between the SS10 and the SS24. I'm not talking about the difference between a spherical knob cutter and straight concave cutters. I might not have been very clear about that in my original post. I agree I use my concave cutters about a billion times more than the knob cutters.

I have a pair straight black Fujiyama  cutters like the SS10, but I'm not very impressed with the craftsmanship (when the blades meet, the stop is still a couple mm from the opposite handle). I know I wasn't the nicest to my tools when I first started bonsai, but I don't think the stop has ever worked as a stop.

Adair, thanks for the info of stainless vs. carbon. Is the quality choice basically between Fujiyama/Joshua Roth, and Masakuni? Is there any intermediate step between the $30-$40 tools and the $140 Masakunis?

Yes those were the tools I thought you were referencing. It is a tough call between the types of metal. I think Masakuni even has stainless with carbon blades or something like that. The carbon does sharpen better, however the stainless seems to hold its blade well, and as long as you take care of them and do not misuse them they will hold that blade for a very long time.

J, the spherical concave cutters adds another dimension in what you can do with one tool. I use tools as much as, probably anyone, if that matters, and I use the spherical concave cutters 10 times the amount of standard concave cutters.Tool preference is a matter of use and familiarity so if you are a "TOOL MAN" then go play. As to stainless vs high carbon its a matter of preference. If you aren't a professional and don't use the tool all day every day you will never know the difference. There are a lot of tool suppliers and there are lots of choices between your two extremes. Check around.

I won a $40 gift certificate to our club's tool store, so I'm going to see what our tool man can get his hands on. I think we usually get our stuff through Dallas, so we'll see what he can scare up. Are the rounded head ones any harder to sharpen?

"Wood" you mind elaborating on the uses of the spherical concave cutters. I am afraid i am not using mine to their full advantage as i use them less than my straight edge concave cutters.

The spherical type just cut deeper and with a concave wound that allows smoother healing. It just elimanates the need after a straight cutting of having to use a knob cutter to concave the wound so it doesnt make a bump when healed.

just saving steps.....

As far as quality, I think for masakuni your better off with some older ones that you cleaned the rust off of. I wont mention any names, but a very prominent Bonsai artist touring around rite now, uses some old cheap tools from like 10 years ago and is not using masakuni. I do like masakuni, but I use the stainless steel PLATED tools. they dont rust like the black ones but they hold a sharper edge like the black ones do.
 My oldest, most reliable tool is a small joshua roth wire cutters. I have used it consistantly since 1994 and I cut all sizes of wire in it. Some times the wire barely fits in it and I cut rite thru. have never sharpened it or repaired it and it would cut thru a school! :D Cost like 23 bucks.
 The bonsai aesthetics tools made by Bob Stevens thru stone lantern are pretty good and I have bought some of those. I have ordered like 10 different times from them and they are always top service and worth the money.
