Another whistle question

[SouthOfSouth]

Hi,

 

A few months ago, I bought two whistles. One was a stainless steel whistle, similar to this

in shape, although I don't think it was quite as well made.

 

The second one is a nickel/silver whistle and generally similar in shape to the first, except that it does not have a tag and hole for a tether. I prefer its tone and taste and can produce a few different notes in practice, but without any way to secure it, I haven't dared take it outside.

 

If I drill a hole near the rim, will it ruin the sound? Alternatively, would it be feasible to glue or solder a tag onto the outer surface? Any other suggestions?

 

Thanks,

 

Kerry
