How to express "with (x) as well" and "even with (x)"


I am trying to express something akin to these sentences:

>   1. **Even** _with_ a spoon, he digs well (でも?)
>
>   2. **Even** _without_ a shovel, he digs well
>
>

* * *

I would also like to express this:

> With a shovel _as well_ , he digs well [implying he digs great with a lot of
> tools]

How would one go about this?

I can see how my example sentences might not be best example, but what I'm
basically wondering is whether adding `でも` or `も` to the particle `で` is
possible, as it with, for example, `に`

`ででも` does sound rather silly to me.




Adding も after で is possible and usual. See [Particles で and も and
でも](https://japanese.stackexchange.com/q/5666).

Adding
[でも](http://dic.yahoo.co.jp/dsearch?enc=UTF-8&p=%E3%81%A7%E3%82%82&dtype=0&dname=0ss&stype=1&pagenum=1&index=113520600000)
after で is also possible, and ででも is not unseen, but the first で is often
omitted.
