It was good point
(1) Since the plug-in part contains the depth of the handle,
I think that the height is well restrained.
(2) Only one bit is attached, but since short bits are already aligned
Useless bits are unnecessary. It is saved to be cheaper than bit set.
I want to improve
(1) The size of the handle is sufficient, but depending on the situation it is slippery.
I think that it is the reason why concave halfway half circumference slips.
Handle shape close to a triangle, the circumference of the circumference of the circle is finer
I think that it will not slip.
(2) I want a prominent color version of yellow or orange.
Regardless of the matter of slipping, this kind of ultra-short starbee is easy to use
I think there is.
