Frequently Asked Questions

Which blade width should I choose?
4 mm and 7 mm for narrow bones and fine work; 9 mm and 12 mm take a wider bite on a broad dorsum. The catalog table above lists every width with its catalog number.

What are the graduations for?
They mark depth up the shaft, so you can see how deep the blade has gone and stop at the point you planned.

Is it used with a mallet?
Yes. The flat striking end is made to be tapped with a surgical mallet, and the shaft transmits the force straight down the blade.

Can these be autoclaved?
Yes. They are supplied non-sterile and re-usable, so clean and autoclave them before each use.

Do you sell the full set of widths?
Yes. Order each width from the selector above, or contact us on WhatsApp and we will quote the complete set together with bulk pricing.

Do you supply bulk or OEM orders?
Yes. Contact us on WhatsApp for bulk discounts and OEM or private-label pricing.
