Also called Scalpel handle
A short, dental-length handle sized for intraoral work, rather than the long shaft the transphenoidal pattern needs to reach a deep surgical field.
A surgical knife handle, also called a scalpel handle or B-P (Bard-Parker) handle, is the reusable steel grip that a separate, single-use blade clicks onto: the handle itself carries no cutting edge. The front end is machined into a flat tongue with a raised rib and a locking lug; the back of the blade has a matching slot, so the blade slides on and locks into one fixed position rather than being screwed or clamped down. Handles are identified by number rather than by name, and each number takes only its matching family of blades: a No. 3 handle (and the longer No. 3L) takes small blades such as No. 10, No. 11, No. 12 and No. 15; a No. 4 handle takes the larger No. 18-No. 25 blades; and a No. 7 is a slimmer, pen-shaped version of the No. 3 fitting. A separate round or hexagonal chuck-type handle exists that grips a blade's tang in a knurled collet instead of the flat Bard-Parker lug, and is sold by overall length rather than by blade number.

Quality control
The inspection step is set by the line you order.
- Economy line
- sample: visual + dimensional
- Clinical line
- sample + boil test
- Premium line
- tighter sample + hardness test
- Executive line
- 100% inspection + laser mark
Finish A color is a second choice, made on top of the line. Colored finishes on request, on any instrument, in addition to the steel line. Evidenced: black · gold · rose gold · blue · rainbow (anodised titanium).
How it is built
- Flat tongue with raised rib and locking lug at the working end (Bard-Parker fitting), blade slides on and locks, not screwed or clamped
- No cutting edge on the handle itself; only the detachable blade is sharp
- Numbered, not named: No. 3 / No. 3L take blades No. 10, No. 11, No. 12, No. 15; No. 4 takes No. 18-No. 25; No. 7 is a slim pen-pattern No. 3 fitting
- Flat, ribbed handle body for the No. 3 / No. 4 family; round or hexagonal, knurled body for No. 5, No. 7 and chuck-type
- Chuck-type round/hexagonal handle grips a blade tang in a knurled collet instead of the flat lug, and is sized by overall length rather than blade number
- One-piece solid stainless steel construction
- Supplied straight, not curved

This describes the surgical knife handle (scalpel handle) as an article. 3 other articles in this catalog share it: the sentence above is what separates this one. This describes the article. The steel, the finish and the inspection step are set by the line you order.
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 sterilization 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.
Customized 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.
