Inquiry about Shield and Buckler rules


I am a new player looking into the rules of shields and noticed there was a section dedicated to Bucklers. I was thinking of using a Buckler (of course abiding by the rules) but I am confused of whether or not using the Buckler to push against a weapon (not the player) is against the rules or unsafe. I intend to use the Buckler to push against the weapon and create an opening for an attack.
Sorry about the lack of response. Normally, deflecting is perfectly fine, but as a lightest touch system, we don't really need to do a ton of manipulation of enemy attacks to open opportunities.

I'm not a marshal so this may be a better question to ask on site with the safety staff so you can show exactly what you are talking about for a more specific answer.
