A school teacher and badminton player, he brings a patient, approachable manner to learning and working with others.

Professional Stringer Qualifications
BSW Accredited Certified Badminton Stringer
Kelvin’s certificate confirms the BSW Level 1 Certified Badminton Stringer programme, Stringer ID BS260703015 and certification number BSSG00260717A. His progression from course learner to accredited stringer reflects his willingness to keep learning rather than rely only on previous experience.
Practical Stringing Skills
Kelvin’s confirmed badminton stringing specialty covers two-knot, four-knot and Around the World methods. His patient approach supports careful preparation, appropriate pattern selection and a steady working sequence.
2-knot Technique
Two-knot stringing is one of the methods listed on Kelvin’s accreditation certificate. His continued practice centres on following the appropriate racquet pattern, handling the frame carefully and finishing the job with attention to detail.
4-knot Technique
Kelvin’s certificate also confirms four-knot stringing. This method uses separate main and cross strings; suitable tie-off points and an orderly sequence help him approach the work thoughtfully rather than rush through it.
Around the World Pattern
Around the World is the third method confirmed on Kelvin’s certificate. Learning different patterns gives him a broader foundation, while the racquet’s design and requirements remain the starting point for choosing an appropriate method.
Badminton Stringer Development

Kelvin plans to bring his BSW-assessed badminton stringing skills to players in Clementi, Singapore.
As a teacher who enjoys badminton, Kelvin wants to understand why a setup suits the player, as well as how to complete it carefully. His ongoing development focuses on:
Following a controlled and repeatable stringing sequence
Discussing string properties and thickness with the player
Checking the frame and treating grommets with care
Choosing suitable tension within the racquet’s limits
Listening patiently to feedback about feel and comfort
Finishing secure knots and checking string alignment
Explaining setup choices in a friendly, clear manner
Badminton Stringing Knowledge
Kelvin’s interest in badminton helps connect stringing knowledge with the feel a player describes on court. His teaching background and patient manner encourage clear conversations about strings, tension and racquet care, while his desire to improve keeps him open to learning more.
His confirmed qualification is BSW Level 1 Certified Badminton Stringer. The certificate references BSS 19020. BSW’s IRSE 24001 education framework, CTS – Certified Trusted Stringer resources and Certified Stringer Pro pathway explain the wider approach to player advice, careful work and professional development.

Stringing Equipment and Care
The supplied photographs show Kelvin learning and practising at an electronic stringing machine, working around the mounted racquet and handling the strings. These real moments illustrate the careful, hands-on work behind his continued development.
A thoughtful equipment routine includes checking the mounting, keeping clamps clean and inspecting the completed racquet. Combined with appropriate string and tension choices, these habits support the steady, detail-conscious approach Kelvin aims to bring to his service.

Personal Badminton and Stringing Background
Eric Chuar describes Kelvin as a humble, easygoing person who is patient with others and genuinely wants to progress. As a school teacher, he is accustomed to working with people. He does not push others to hurry; he concentrates on doing his own work well and finding ways to do it better.
Kelvin enjoys playing badminton and has been stringing for some time. Pursuing BSW accreditation is another step in that ongoing journey. His friendly manner, patience and willingness to listen make him someone players can feel comfortable approaching to discuss their racquet setup.
