Also called cast knife
A single-blade hand knife used to cut and trim plaster-of-Paris and synthetic casting material, either while it is still workable or after it has set. Unlike plaster shears or a plaster saw, it is a fixed blade held and drawn like a knife, not a hinged or toothed cutting instrument. The point is usually rounded or blunt so the blade can pass close to skin under a cast without cutting it.
Minimum order 300 instruments The minimum for orthopedic instruments. Mixed orders are quoted against your list.
Lead time Instruments ~2-3 weeks · full sets ~4-6 weeks after advance.

How it is built
- Single fixed blade, not a hinged (scissor-type) instrument
- Straight cutting edge, ground on one face
- Point is typically rounded or blunt rather than sharp-pointed
- Handle is either forged in one piece with the blade or a separate wood/composite grip fixed to a tang
- Made under several named patterns (e.g. Esmarch, Hopkins, Reiner) that differ mainly in handle material and blade length
Patterns Esmarch · Hopkins · Reiner

Material and quality
| Line | Steel | Origin | Finish | Inspection |
|---|---|---|---|---|
| Economy line | AISI 410 | Pakistani or Taiwanese | satin, passivated | sample: visual + dimensional |
| Clinical line | AISI 420 | Pakistani or German | satin, passivated | sample + boil test |
| Premium line | AISI 420-440C | German or Japanese | fine polish, passivated | tighter sample + hardness test |
| Executive line | AISI 440C | German or Japanese | mirror polish, passivated | 100% inspection + laser mark |
This is the steel each line is made from as standard. A different origin can be supplied on request (a lower grade in Japanese steel, for example), agreed on your order.
Premium is the line where the choice is yours: 420 or 440C, agreed on your order. Economy is always 410 and Executive is always 440C. Those three are the instrument steels. Hollowware and sterilisation containers are made in AISI 202 on a Clinical order and AISI 304 on a Premium or Executive one, and they are not offered in the Economy line at all, which is the section above.
True of every order
Instruments are marked to the buyer's requirement (TGI, unmarked, or the buyer's own brand), agreed on the order.
Customised packaging is part of what TGI supplies. Your own printed boxes, your labels, your brand on the pack, or plain export packing, whichever your market needs. The packing for your order is agreed with you and confirmed on the order.
Manufactured under the quality management system covered by TGI's ISO 9001:2015 and ISO 13485:2016 certificates. Certificate numbers and the issuer's registry are on the certification page. Open the certificates
Every batch of steel is ordered to a specified grade and arrives with the mill's own certificate, which identifies the mill and states the grade. TGI checks the material at the factory against its own requirement before it goes into production. That check is TGI's own inspection, not an independent laboratory test.
TGI manufactures in its own factory in Sialkot and also supplies articles made by contracted partner workshops, to TGI's specification. Which applies to a given article is confirmed on your order.
