Take good care of your OBU. They will pay you back.

Like all relationships, there's a bit of give and take. Look after your OBU and they will continue to be a committed and dependable partner for you. Treat them badly? It will be like sushi left in the sun. No good.


Your OBU come with black finger inserts already placed in the scissors. Please remove as required.

Your OBU also come with scissor oil, a tension key (Masuta range only) and a cleaning cloth. Please keep in a safe place.

Your protective OBU box has a foam insert to keep your scissor oil (and key) secure during shipping. This foam is removable to allow you to store two pairs of scissors, or anything else of your choice in the box. 

Your OBU also come with a protective suedette pouch. It is suggested that you keep your OBU in this for protection when not in use.


Before you cut with your new OBU, ensure you alter them to the correct tension as this provides better balance and an appropriate level of effort during cutting.

If tension is too loose, your scissors will fold and bend hair.

If tension is too tight, your scissor blades will prematurely wear, requiring more frequent sharpening as well as increased resistance. This will result in increased user fatigue and potential sustained injury.


Do not adjust the tension on your scissors while the blades are open.  This eliminates the risk of nicks to the blades.

Step One:

Ensure your scissors are clean and oiled.
Hold scissors vertically by the thumb loop and lift finger loop into a horizontal position.
Jiggle the two blades slightly against each other.

Step Two:
Let go of the finger loop. The blade should fall slightly and close halfway up the other blade.

If the blade falls completely closed, your tension is too loose.

If the blade doesn’t move at all, your tension is too tight.

Step Three

Adjust the tension by tightening the screw (MINARAI range) or using the tensioning key provided (MASUTA range).

Simply take it one notch at a time, and repeat steps one and two above.

Note that new scissor blades need a few days to settle. Avoid heavy pressure or cutting thick sections for the first few days.


 If in doubt don’t cut. 

Never complete a cut if the section offers resistance. Forcing a cut means the scissors are too light for the task and can damage blade edges.

Clean your scissors between every haircut. 

When blades are covered with hair or moisture, corrosion can occur. Regular cleaning keeps blades sharper, longer.

If foreign objects are stuck on scissors, use hot water to clean and dry thoroughly with towel before continuing with cleaning process.

Always use a soft cleaning cloth to wipe scissors clean.

Oil your scissors at the end of every day. 

A coating of oil protects scissors keeping moisture out and the scissor action smooth.

Use only scissor oil for lubrication. A scissor oil pen is provided with every OBU purchase. Please note that other oils may damage the blades and scissor mechanisms.

Ensure scissors are clean and dry. Open scissors fully and place a small drop of OBU scissor oil on each blade at the balance face which is just above the centre screw. Open and close scissors gently so the oil spreads over the balancing face.

Store your scissors safely. 

Secure scissors and store in your OBU case and protective pouch, when not in use. This includes between cuts and at end of day. Do not leave scissors wet or dirty as rust and corrosion may occur.

Servicing & Sharpening

Replace missing or worn parts as soon as possible.

If you drop or bang your scissors, please get them serviced as soon as possible. Improper alignment can cause damage to your hands and wrists. It is also suggested that you always have a backup pair of scissors in the event your preferred pair needs to be serviced.

Always take your OBU scissors to a reputable sharpener as an incorrect process or equipment can damage your scissors and void your warranty. Required frequency varies between 6 months – 2 years depending on use.

If you do not have a scissor sharpening scissor service that you currently use, we suggest that you ask for recommendations from your peers and colleagues.
