Was initially concerned about purchasing based on others reviews however my experience has been nothing but good with this tool set. The main concerns I read in other's comments were:1. Tools broke while trimming/cutting2. Tools arrived rustedNeither of these issues occurred with the tools I received.

They arrived sharp with no visible rust and the cutting area of all tools was very sharp. Initially I was very conservative about my limb trimming based on the concerns around tool breakage however I have since been able to easily cut 1/4 to 1/2 limbs without concern.

I'm sure this is dependent on the hardness of the wood you're attempting to trim however I would say if while trimming the cutting edge will not slice any further into the wood and instead the pressure you are creating at the handle is what is driving the tool further than you likely need to sharpen the tool or use a different tool.

I know that certain Bonsai tools are essential for grooming your Bonsai. That being said, I am a beginner and some tools I am apt to buy as a beginner. The spherical cutters work well and are essential for cutting close to the small branch.

The other flush cutter gets you as close. Also you cannot do these tasks with a typical set of gardening cutting tools.I tried-no way. As I get further into Bonsai, I will probably buy a better set as I do with my other tools once I know I will actually spend the time and effort but for the beginner I think they work well.

Those Bonsai enthusiasts who disagree with me, have mercy, I am a beginner and as any beginner, you start affordable and then as you become more experience, you buy the best you can for the money such as my woodworking tools.

There are cheaper sets on amazon, mostly with black finishes. They look like they're all from the same manufacturer. I bought one of those before I bought these. The black ones are trash. The cutting surfaces are poorly finished and don't even occlude properly.

This can seriously mess with cuts to wood. These on the other hand are of decent quality. I'm sure they won't hold an edge as well or last as long as legitimately high-end bonsai tools, but these are more than good enough to start with and should last you years with proper care.

Like the other tools I have bought before by Tian Bonsai tools (or Paul Bonsai -a pseudonym, I presume-) it looks perfect. I am completly satisfied. The size of the tool is perfectly adapted at the roots commonly found -for the little one, there are scissors.

There is just to wait to see how it will be after some years. Note that my first tools (Paul Bonsai - from USA) were comming very faster than this one (Tian Bonsai Tools -from China-).

I was a little worried at first since their were no reviews on the product. I am so happy I went for it anyway. This is a great set of bonsai tools. They all came surprisingly sharp for scissors and branch/root cutters.

I worked on one of my bonsai and all the tools were great from the sheers, rake, root cutters all the way down to the leaf trimmer. I would defiantly recommend to anyone who does not want to spend 3-6 hundred dollars on bonsai tools.

There is a three year guarantee.

Bonsai Knob Cutters Buying Guide

Fredrick Kidd

Price

It might be costly to buy a practical and quality tool for bonsai enthusiasts. The case is that a specialized tool can be a necessity when you become more professional. When choosing tools for bonsai purpose, you might need a complete set of units. That comes with a considerable amount of investment. A practical choice is to choose the most frequently used tools firstly. And then turn to further purchase when you need it. Buying a cheaper one does not mean that you have to compromise on its quality. It might cost much more when the cheaper models have to be replaced after short use. If you want to get the best value, more investment in quality can be considerable.

Quality

When considering the price, you have to evaluate the quality as they two are closely linked in most cases. A knob cutter with better quality can be fairly light that takes less effort for prolonged jobs. A lot of models use supreme materials of stainless steel that can be rust-proof and durable. The quality metal of fabrication maintains sharp edges even after long time use. When thinking about this, you have to pay attention to both its materials and the design. That means an ergonomic designed tool which can fit your palm and tasks will be better for your needs. However this depends on personal preference. If you need to a tool to use for temporary, a reliable and capable tool can be considerable.

Size and weight

The bonsai knob cutters available on the market come with various size and length. A suitable size depends on what you will use it for. On one hand a reasonable level of size and weight makes it handy and easy to use. A larger one can carry more stress and strength but it might be heavy and exhausting for long hours. On the other hand the size cooperates with the branches to be cut. That means a small size tool could be incapable to handle long branches over its length.

Durability

It is important to choose a durable tool for bonsai purpose that can last for long time. You would not want replacement of the tool when you are doing a bonsai art. The materials of the handle, the edges and blades should be of reliable quality. Following full consideration of factors above, you can check reviews from other customers.
