There are literally dozens of types of Bonsai Tools that have evolved over the millennia, tool that are specialist in their use, like the branch splitter; and some like the Jin Pliers, which have evolved from everyday home utensils. The Jin Plier are no more than Chinese Tongs used to hold the hot wok with its Angled tapered head and nose.
Over the years, Bonsai Tools have become essential for Bonsai professionals. Bonsai trees that are cut with simple scissors can not achieve clean and sharp cuts as Bonsai Tools do.
I shall present the tool grouped by how they are applied to everyday Bonsai maintenance tasks, like Pruning, Re-potting, Shaping and Wiring, and Carving, Feeding and Watering. I have found a nice video on youtube that gives a glimpse on Bonsai tools for beginners. It explains why you should start with cheaper tools first.
Bud & Fine Twig Shears (Koeda Kiri Hasami) - These long reach scissors are designed for pruning delicate branches, twigs and buds. Their long slender handles are ideal for those difficult to reach places.
General Purpose Shears (Ashinaga Basami) – These comfortable shears are for your every day
Branch & Root Shears (Hasami) - This heavy duty tool allows you to prune your Bonsai’s thicker Roots and Branches. Its broad blade allows you raverse the fully width in one clean cut, allowing for smooth and clean cut end to end, and good for healing cleanly and quickly. To use, for pruning fine to medium branches and roots. Do not walk into your Bonsai Garden without them. The large handles allow you to use all your palm and fingers to exert maximum pressure.
The Concave Branch cutter (Mataeda Hasami) - is used to remove a whole branch at the trunk. The concave cut left behind fills over itself leaving little or no scar.
The Knob cutter (Kobu Kiri Hasami) - leaves an almost spherical cut on the branch thereby allowing it to heal flush with the surface.
Leaf cutter - Easy to use, spring loaded leaf cutters, with razor sharp blades, it makes defoliating trees a breeze.
Root Cutters – In shape almost like the Branch splitter, but the cutting lips are not as deep as those of a branch splitter, and the lips are positioned at a slight angle where as the Branch Splitters are positioned horizontally. Ideal for cutting the thicker tap roots and adventitious roots and for nipping out root stumps closer to the trunk.
Root Hooks – Single and Multi-pronged invaluable tool when re-potting. The single pronged hook is used to tease out individual and difficult roots, while the multi-pronged hook is used to untangle root balls.
Drainage Screens – Draining Sieves play two roles, one it prevents the lost of soil from the drainage
holes and second it helps keeps insects and other pest out of the pot. Use a non-clogging variety of drainage screen.
Rakes – Like root hooks are used on smaller root balls, and to plane or rake the surface of the soil on a Bonsai pot to remove debris or to agitate the top soil if it has got compacted or to remove surface weeds.
Tweezers – have a multitude of task but are mainly used to remove weeds, unwanted buds.
Spatulas – Very important tool, make sure you get a strong heavy metal grade spatula, is used for many tasks around the potting shed, but I think the most important of them is to tease those stubborn little trees out off their pots when you need to re-pot them.
Sieves – To ensure that you use just the right size grit or growing medium for you bonsai.
Scoops – In valuable little helper, beats having to use your hand to fill the pot with, some of these handy scoops even come with an in built sieve.
Tamping Trowel - Used to tamp down soil when re-potting or after mixing in solid bonsai feed.
Coir Brush – The brush end is used to smooth down soil surfaces and give a finished look, or just brush-off dead leaves and debris of the surface. The handle end made be used to clean or rub off branches and trunks unsightly loose bark or lichen, or perhaps even the odd pest.
Shari and Si Diao Carving Tool - are used for creating and enhancing the quality of deadwood display on Bonsai.
Hand saw – for use in lots of little task. Look for a pull saw version if you can find one. Essential for when you are on those collecting field trips.
Grafting Knife – ideal for carving and also for propagation purposes.
