One can also actually good tips with him, but has to import the pin exactly vertically into the hole and hold on tight. Furthermore, one must remember himself when to pull it back, there is no stopping Spitz.
The white Spitzer used for sharpening of very sharp peaks, the gray standard Spitzer pointed the pins not so extremely sharp (what a phrase!). Both the knife sharpeners are interchangeable.
Something crash makes the Spitzer, but that's still acceptable.
Can be draining him too easily and a broken mine can be similar with a fine thin knife also good to get out of the sharpener.
In the old pins the wood can break, no matter what you choose here Spitzer and not each pin can withstand an extremely sharp tip. This one must try but himself.
All in all a good quality (Made in China) at an acceptable price. I'm curious how long he holds (but one has a two year warranty on it). Recommended if you want tips many pins.
PS: According to the manufacturer not suitable for pastel and charcoal pencils.
