Meaning of どく in sentence


I have a sentence in Haruki Murakami's 海辺のカフカ which reads:

> でも形而上的であり象徴的でありながら、同時にそいつは千の剃刀のようにする **どく** 生身を切り裂くんだ。

I understand the first part of the sentence as:

> May it be metaphysical or symbolical, at the same time it's like a thousand
> razors... ripping apart...

But I don't get the meaning of that どく part. I don't believe it's 毒, as it's
written in hiragana.




「するど **く** 」 is the [連用形]{れんようけい} (continuative form) of the adjective 「するど
**い** / 鋭い」 = " ** _sharp_** ".

"sharp" ⇒ "sharply"

It is conjugated into its 連用形 so that it can modify the following verb
「[切]{き}り[裂]{さ}く」 = "to rip up".

One cannot say 「するど **い** 切り裂く」. I feel like I am talking about 連用形 almost
everyday here (along with relative clauses). Wonder how properly those are
taught in Japanese-as-a-foreign-language.

Finally, 「[毒]{どく}」("poison") or any other **noun** will not fit in
grammatically.
