HMX Blue Topaz vs. KTT F2
An in-depth look at the HMX Blue Topaz and the KTT F2 switches—which one is the best fit for you?
Overview
The HMX Blue Topaz and KTT F2 are two mechanical keyboard switches that offer unique experiences for users seeking a linear switch option. The Blue Topaz stands out for its smooth actuation and lightweight feel, making typing a breeze with its clacky sound signature and eye-catching glitter housing. On the other hand, the KTT F2 switches offer a distinct hollow sound and medium-light weightiness, providing a comfortable typing experience with a lightly textured feel. While the Blue Topaz is easier to press and offers a clacky typing experience, the F2 provides a feathery and subtle feel with a subdued sound profile. Both switches have their own strengths and characteristics that cater to different preferences. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
In comparing the housing materials of the HMX Blue Topaz and the KTT F2, both switches feature a polycarbonate top housing that creates a sharper, higher-pitched, and crisper sound profile. This is due to the relatively stiff nature of polycarbonate, which leads to a clear and resonant sound. Aesthetically, both switches benefit from the translucency of polycarbonate, especially if RGB lighting is used. However, where the Blue Topaz differs is in its nylon bottom housing, which elicits a deeper and fuller sound profile compared to the F2's polycarbonate bottom housing. Nylon is softer and absorbs more sound, resulting in a duller and rounder sound when typing.
Despite their differences in bottom housing material, the impact of the housing materials on overall sound profile and typing experience can be perceived differently between the HMX Blue Topaz and the KTT F2. The qualities of the bottom housing, such as depth and fullness in sound, will be more apparent when pressing down on the switch, affecting the bottom-out sound and feel. Conversely, the qualities of the top housing, like crispness and resonance, will be more noticeable when letting go of a key. While both switches feature similar polycarbonate top housing, the choice of nylon for the Blue Topaz's bottom housing offers a contrasting sound experience compared to the F2's polycarbonate bottom housing.
In conclusion, the housing materials of the HMX Blue Topaz and the KTT F2 play a crucial role in shaping the sound profile and typing experience of each switch. Both switches benefit from the crisp and resonant qualities of polycarbonate in their top housing, enhancing the overall sound output. However, the Blue Topaz sets itself apart with its nylon bottom housing, providing a deeper and fuller sound profile that differs from the F2's polycarbonate bottom housing. The combination of these housing materials results in unique typing experiences for users of each switch.
Weight
The HMX Blue Topaz linear switch is lighter in terms of actuation force and bottom out force compared to the KTT F2 linear switch. The Blue Topaz has an actuation force of 40 grams and a bottom out force of 48 grams, while the F2 has an actuation force of 43 grams and a bottom out force of 53 grams. The Blue Topaz offers a lighter typing experience, making it ideal for those who prefer a lighter touch for extended typing sessions or gaming. On the other hand, the F2 provides a slightly heavier push feel, which can cater to users who enjoy a more substantial typing experience. Overall, the choice between the two switches will ultimately depend on personal preference for actuation and bottom out forces.
Travel distance
The Blue Topaz linear switch has a travel distance of 3.9 mm, while the KTT F2 linear switch has a slightly shorter distance of 3.5 mm. Both switches fall within the range of shorter travel distances, making them ideal for users looking for quick and responsive keystrokes. Gamers, in particular, may prefer the shorter travel distance of the F2 for faster response times during intense gameplay. However, those who prefer a bit more depth in their keystrokes may lean towards the Blue Topaz with its slightly longer travel distance. Ultimately, the choice between the two switches will depend on personal preference and typing style.

Consider your typing style, sound preference, and desired typing feel when making your decision between these two switches. Ultimately, both switches offer unique characteristics that cater to different preferences, so choose the one that aligns best with your typing needs and preferences.
