Total ice axe newb here. Not talking climbing, but a multipurpose tool for winter walking on icy trails. I have always used ski poles in the past, but sometimes a sturdier tool would be helpful
I see a number of models in the sub-$100 category. How strong are they really?
A proper ice axe is rated. The UIAA rating is either 'B' (basic) or 'T'. (technical) Both are used for building dead man snow ankers, so plenty strong. 200KG pick and shaft for the basic rating and 400kg for the technical.
I would also want to be able to chop toeholds in icy trails and cat holes for sanitation if necessary. (Doubly useful if a few winter trail newbs are following in my footsteps.)
The basic ones have a adze, but the more technical ones, well they might not have them. You need the adze for chopping. Side note, basic ice axes are generally very good toilet roll holders. Just push the shaft in the ground and slide the roll over the pick. Do following park rules.
An added bonus would be as a "dissuader" to dogs running off leash on park trails, or urbanized coyotes that have lost all fear of man. A little reach goes a long way, and ski poles are a bit too flimsy.
Thoughts? Recommendations on brands? Better than mounting a hardware store mini-pick on a sturdy walking stick?

For your use a simple straight shaft sounds like the one to pick. The cuvrve is nicer when you have to climb steeper things with it. Check if the head is comfortable in the type of grip you will be using. The black diamond seems to be nicer to grip, if you using it walking stick mode, while the Grivel ones are better if you are holding the shaft, ready to brake mode.
If you want good chopping capability, some weight would be nice.
