BP clasps are OK regarding security. 5 digits clasps can be adjusted more so than 6 digit ones. They are thinner metal so are more bendable to make them close tighter, or make the fliplock more snug.
BP 5 digit bracelets are also known for having some sharp edges. I've spent up to an hour on every one I've had smoothing sharp corners and edges. Just the price we have to pay.
Thanks so much for this info! Just reached out to Sead for a coke as well.
