Where to get scalpel who's blade turns red when flamed?

I've bought several different scalpels locally the blades of which do not turn red when flamed. I have to really time it correctly, otherwise the whole thing becomes too hot to handle. It also takes FOREVER to do a large number of agar transfers when you're waiting up to 30 secs for the thing to heat up. The same happens with an exacto knife.
Where (online or elsewhere) can I get a scalpel the blade of which turns red when heated (like in RR's videos)?

It's not the blade thats the problem, its the heat source.

I second that. Get a butane lighter...it only takes a few seconds.

I use an alcohol lamp... It turns everything else red (inoculation loop, needles)
The problem lies in the blade (therein the scalpel) which is too thick.

As mentioned above, it's your heat source. An alcohol lamp burns about the same temp as a bic lighter, its just a lot easier to sustain since you dont have to hold a button and let your lighter cool down after 45 seconds of use.
Go buy a butane lighter, the kind that literally looks like you're about to weld something when you light it. You can buy them at most gas stations for like 5-10 dollars.
Needs to be moar hot.

Get a scalpel from fungi.com. They have replaceable blades, which are thin enough to heat up. Scalpels that are one piece will get too hot to hold if you try to heat them with a torch. RR
